Thank you for your report. This fix need to pick up more patches from git. It takes some time.

Comment 2 Tom "spot" Callaway 2009-03-11 18:23:09 UTC

I'm working on this in rawhide, it should be trivial to push the changes back to F-9/F-10.

Comment 3 Tom "spot" Callaway 2009-03-11 22:31:37 UTC

There are patches checked into CVS for this in F-9, F-10, and devel. Updates will have to wait for everyone to be okay with the reordering of @INC (bz 489221).
