Hi,

Recently, trying to do 

  yum --enablerepo=sl-fastbugs update

on an x86_64 SL 5.9 system (using a local mirror of the repo) fails with:

file:///data/repo/scientific/59/x86_64/updates/fastbugs/repodata/primary.sqlite.bz2:
[Errno -3] Error performing checksum

The cause seems to be that the file fastbugs/repodata/primary.sqlite.bz2
now contains some sha256 rpm checksums (added in the most recent
fastbugs updates; eg esc, glibc) that SL5 yum does not understand.
Perhaps the associated data was created on an SL6 system?

The problem can be worked around with:

  yum  --enablerepo=epel install python-hashlib

but the repodata should probably be fixed. Thanks.
