Bugzilla Bug 128472

unable to emerge kde. 2 packages that provide ghostscript block each other.
using USE="-cups" will allow some of it to be installed (like if i try to
emerge qt by itself).

echo "app-text/ghostscript-gnu" >> /etc/portage/package.mask and run 'emerge
-pv kde' again, so that we know which ebuild has hardcoded dependency on
app-text/ghostscript-gnu.

try emerging virtual/ghostscript

The next sync will remvoe the PROVIDE line in the ghsotscript-* ebuild which
presumeable caused this.
