When building games-strategy/freeciv with the Qt 4 client, it assumes that the only possible locations for the Qt libraries are the standard system directories and "/usr/lib/qt4" (even on amd64 with SYMLINK_LIB=no, where that is where *32-bit* versions would be kept). This causes the build to fail during ./configure.
the qt stuff shouldn't be exposed. It's not ready to be used. I removed the qt4 option from the ebuild. You should file a bug with upstream though so they fix up the build system so that when the qt client is ready this issue doesn't return.
