There are hard coded dependancies on XFree86-xfs package, which needs to be fixed before xorg-x11 can be enabled in the development tree. The following is found in the spec file: BuildPreReq: XFree86-xfs VFlib2
I fixed these and some other issues in ttfonts-ja-1.2-34 and built new packages in dist-fc2. Closing as 'RAWHIDE'
