I hit this when trying to rebuild allegro: http://koji.fedoraproject.org/koji/getfile?taskID=194562&name=build.log arts-devel used to Requires: glib2-devel, now it no longer doesn't, but artsc-config still wants it: [hans@localhost ~]$ artsc-config --libs -lartsc -lpthread -lgmodule-2.0 -ldl -lgthread-2.0 -lrt -lglib-2.0 [hans@localhost ~]$ artsc-config --cflags -pthread -I/usr/include/kde/artsc -I/usr/include/glib-2.0 -I/usr/lib/glib-2.0/include [hans@localhost ~]$ This causes the ./configure from allegro to no longer detect arts (and if it did detect it, building would probably fail) : configure:7930: checking for arts_init configure:7953: gcc -o conftest -pthread -I/usr/include/kde/artsc -I/usr/includ /usr/bin/ld: cannot find -lgmodule-2.0 I'll work around this for now by BuildRequiring glib2-devel from allegro.spec, but others will get hurt by this too, so please fix this.
Doh, fixed. %changelog * Mon Oct 15 2007 Rex Dieter <rdieter[AT]fedoraproject.org> 8:1.5.8-3 - -devel: +Requires: glib2-deel (#331841)
