When yum tries to acces yjl repository, http://yellowjacketlinux.fileburst.com/yum/yjl/el5/i386/yjl-misc/repodata/re... it gets back

Not Found The requested URL /yum/yjl/el5/i386/yjl-misc/repodata/repomd.xml was not found on this server.

Few days ago everything was OK. This repository is needed for the gnumeric install on CentoOS 5.1.

Is there an alternate repo available for the gnumeric ?
