It is not a problem in avahi, the qt-mt.pc file is installed by the qt package in a non-standard location, meaning /usr/qt/3/lib/pkgconfig instead of /usr/lib/pkgconfig, where all other .pc are located. They should properly set PKG_CONFIG_PATH so that pkg-config can find the files. I'll get in touch with them.
Ok, current baselayout and portage together with qt-3.3.6-r1 should solve this issue. baselayout/portage now have support for PKG_CONFIG_PATH in /etc/env.d and the qt ebuild should install an env.d entry with an appropriate PKG_CONFIG_PATH.
