a new version of doxzgen is available. The new reimplemented doxywizards depends on qt4!
Created attachment 176855 [details, diff] Doxygen-1.5.8 patch I have made some changes to 1.5.7.1 ebuild (mostly s/qt3/qt4). Had to manually export QTDIR in order to compile doxywizard, I don't know why "inherit qt4" didn't set it properly. I've tested it with USE="doc latex qt4" ARCH="~amd64" on Portage 2.2_rc19 (default/linux/amd64/2008.0, gcc-4.3.2, glibc-2.9_p20081201-r0, 2.6.27-gentoo-r7 x86_64)
Works great with USE="-doc latex qt4" ARCH="~amd64" on Paludis-0.34.1.
Yeah, looks like the qt4 eclass doesn't provide everything (even though it looks like eqtmqke4 should do it). The new one is more or less like the previous one, except for some additional environment vars.
I think, the doxygen-1.5.8 ebuild should also support the splitted qt libs, i.e. depend on x11-libs/qt-core etc. alternatively.
