There are hard coded dependancies on XFree86-libs package, which needs to be fixed before xorg-x11 can be enabled in the development tree. /mnt/redhat/test/rawhide-latest/i386/Fedora/RPMS/tk-8.4.5-6.i386.rpm: XFree86-libs I haven't investigated this deeper yet, but will update the report unless it's fixed before I get to looking deeper myself. ;o) Most likely, this is just a broken dependancy on XFree86-libs that should instead be XFree86-devel.
Fixed in tk-8.4.5-7 in rawhide
