The files do contain the -L setting but pkg-config should strip them out.
$ grep Libs: /usr/lib64/pkgconfig/{dbus-1,glib-2.0}.pc
/usr/lib64/pkgconfig/dbus-1.pc:Libs: -L${libdir} -ldbus-1
/usr/lib64/pkgconfig/glib-2.0.pc:Libs: -L${libdir} -lglib-2.0
$ pkg-config --libs dbus-1 glib-2.0
-ldbus-1 -lglib-2.0
Yours didn't.

Ok, sounds like a detail I didn't know about PKG_CONFIG_PATH.

Right.

Those variables are for qmake's internal use, it doesn't apply to pkg-config.
If your pkg-config printed those paths, then pkg-config has a prpblem.
