Description of problem:
The upstream of xpyb and libxcb are different, they have a different release version.
It seems like xpyb should be packaged separately, bundling two different project is agaist fedora policy.
Also, do you mind to update the xpyb to the version 1.2?
This bug appears to have been reported against 'rawhide' during the Fedora 14 development cycle.
Changing version to '14'.
More information and reason for this action is here:
No longer an issue in rawhide.
