Please remove the optional dependency on x11-libs/qt:3 as Qt3 is no longer supported and scheduled for removal. Obviously this can only happen when packages depending on qscintilla have been fixed.
I checked all reverse dependencies, according to: http://tinderbox.dev.gentoo.org/misc/rindex/x11-libs/qscintilla http://tinderbox.dev.gentoo.org/misc/rindex/dev-python/qscintilla-python The only "problematic" package is dev-python/PyQt (which will be masked and removed later) and the transitive closure of its reverse deps: http://tinderbox.dev.gentoo.org/misc/rindex/dev-python/PyQt
But as qt4 will be the only option when we remove qt3 support, that means that we will drop the qt4 useflag as well, which in turn means that all packages depending on qscintilla{,-python}[qt4] will need to have their use dep removed at the same time.
Fixed. All old cruft p.masked.
