The output of the command `gnome-config --libs gnome` is: -L/usr/lib -L%prefix/lib -lgnome -lgnomesupport -lesd -laudiofile -lm -ldb1 -lglib -ldl Notice "%prefix/lib" in there (not supposed to be) - This produces an error whenever compiling something that uses gnome-libs & gnome-config, because %prefix is not a valid pathname.
Fixed as of gnome-libs-1.2.4-3.
