Packages get masked for several reasons.

Funtoo uses Package:Ego, which sets profiles, adds/removes mix-ins, etc. As such the masking of packages now generally happens via a lack of keywords.

For example, when attempting to emerge QGIS we receive this message:

!!! All ebuilds that could satisfy "qgis" have been masked.
!!! One of the following masked packages is required to complete your request:
- sci-geosciences/qgis-3.18.3::science-kit (masked by: missing keyword)

To unmask this package we need to add the following to /etc/portage/package.accept_keywords:

root # echo "sci-geosciences/qgis **" >> /etc/portage/package.accept_keywords

This particular package needs one other package unmasked as well so we will also add the following:

root # echo "sci-libs/geos **" >> /etc/portage/package.accept_keywords

Depending on the packages being unmasked there may be an additional step necessary and that is to add some USE flags to /etc/portage/package.use such as the above example needing four USE flags added. For this we need our package.use file to contain the following:

/etc/portage/package.use

# required by sci-geosciences/qgis-3.18.3::science-kit
# required by qgis (argument)
>=sci-libs/gdal-3.3.0 geos
# required by sci-geosciences/qgis-3.18.3::science-kit[python_single_target_python3_7,python]
# required by qgis (argument)
>=dev-python/PyQt5-5.15.2 printsupport designer sql network
# required by sci-geosciences/gpsbabel-1.5.4-r1::science-kit[gui]
# required by sci-geosciences/qgis-3.18.3::science-kit
# required by qgis (argument)
>=dev-qt/qtwebengine-5.15.2 widgets
# required by sci-geosciences/qgis-3.18.3::science-kit[python_single_target_python3_7,python]
# required by qgis (argument)
>=dev-python/qscintilla-python-2.11.6 -python_targets_python2_7
# required by sci-geosciences/qgis-3.18.3::science-kit[python,python_single_target_python3_7]
# required by qgis (argument)
>=dev-python/owslib-0.17.1 -python_targets_python2_7

Once all required USE flags are in you should be able to merge the desired package.

 Packages get masked for several reasons.
-Portage uses [[Portage_Profiles]], which are used to define basic system settings.
+Funtoo uses [[Package:Ego]], which sets profiles, adds/removes mix-ins, etc. As such the masking of packages now generally happens via a lack of keywords.
-Masking of packages also happens on a profile basis.
-You can look at ''/usr/portage/profiles/package.mask/'''profile''''' for example:
+For example, when attempting to emerge QGIS we receive this message:
+<console>
+!!! All ebuilds that could satisfy "qgis" have been masked.
+!!! One of the following masked packages is required to complete your request:
+- sci-geosciences/qgis-3.18.3::science-kit (masked by: missing keyword)
+</console>
-{{file|name=/usr/portage/profiles/package.mask/00-gentoo|body=
+To unmask this package we need to add the following to /etc/portage/package.accept_keywords:
-# Dev E. Loper <developer@gentoo.org> (28 Jun 2012)
-# Masking  these versions until we can get the
-# v4l stuff to work properly again
-=media-video/mplayer-0.90_pre5
-=media-video/mplayer-0.90_pre5-r1
-}}
-First you see how added the mask, then an explanation why it was added followed by the masked package including version.
-Now if you want to unmask one of those packages you have several possibilities to do so.
-* Let emerge do it for you
 <console>
-###i## emerge --ask --autounmask-write =virtual/package-0.1.2
+###i## echo "sci-geosciences/qgis **" >> /etc/portage/package.accept_keywords
-###i## dispatch-conf
-###i## emerge --ask =virtual/package-0.1.2
 </console>
-* doing it manually for a specific version
+This particular package needs one other package unmasked as well so we will also add the following:
 <console>
-###i## mkdir -p /etc/portage
+###i## echo "sci-libs/geos **" >> /etc/portage/package.accept_keywords
-###i## cd /etc/portage
-###i## echo "=virtual/package-0.1.2" >> /etc/portage/package.unmask
