I'am trying to solve BuildRequires for different distros but for some of them I can never find any packages.
For example this is never succesful: $ osc search -s -B RHEL-6 ...
and this never finds RHEL-6 packages: $ osc search -s ...
Also I'am not sure what packages I could expect for RHEL-6.
For example libedit-devel should be there, see http://ftp.redhat.com/pub/redhat/linux/enterprise/6Server/en/os/SRPMS/ or http://ftp.scientificlinux.org/linux/scientific/6.0/i386/os/Packages/
but obs says: unresolvable: nothing provides libedit-devel
