[CentOS] ycl repository NOT FOUND (needed for gnumeric install)

[Primorec]

When yum tries to acces yjl repository,
http://yellowjacketlinux.fileburst.com/yum/yjl/el5/i386/yjl-misc/repodata/repomd.xml
 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 ?
