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. See http://fedoraproject.org/wiki/Packaging:Guidelines#Bundling_of_multiple_projects 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: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
No longer an issue in rawhide.
