[Cooker] Imlib SRPM is bad

[Chris Spencer]

I just tried to compile the current Imlib SRPM in cooker and it fails with
the following error:

+ tar jxvf /usr/src/RPM/SOURCES/imlib-pofiles.tar.bz2
tar: invalid option -- j
Try 'tar --help' for more information

Just thought that I would pass that on to the packager...
