dev-libs/qt:4 has been masked to require dependent ebuilds use the split packages rather than the meta-ebuild (see bug #217161 comment 11). Since >=x11-themes-mythtv-themes-0.22 only needs qmake (and not any qt libraries), it is safe to depend on x11-libs/qt-core:4 (updated ebuild attached) Reproducible: Always Steps to Reproduce:
Created attachment 199269 [details] Updated ebuild depending on x11-libs/qt-core:4
fixed. thanks.
