[fedora-arm] Source repositories unavailable?

[Norbert Wegener]

I installed a f12 on a Sheeva Plug and it works fine.
Now I wanted to compile a rpm package from source.
I enabled all repos in /etc/yum.repos.d/fedora.repo
/etc/yum.repos.d/fedora-updates.repo
Then
[root at fedora-arm yum.repos.d]# yum clean all
Cleaning up Everything
root at fedora-arm yum.repos.d]# yumdownloader --source mysql-server

Trying other mirror.
Cannot retrieve repository metadata (repomd.xml) for repository:
fedora-arm-source. Please verify its path and try again

Is there another source for the srpms available?
Thanks
