delta rpm compose debugging change

[Kevin Fenzi]

Greetings. 

Of late openoffice.org and a few other packages have been not
generating delta rpms in pushes. ;( 

They error with: 

Error genDeltaRPM for chunkd: exitcode was 256 - Reported Error: bad cpio archive

But looking later at both rpms, things seem fine. ;( 

I've talked with jdieter and we would like to add in more debugging: 

<jdieter> nirik: We're still having the "bad cpio archive" with
openoffice.org updates
<jdieter> I have a patched version of deltarpm available at:
http://www.lesloueizeh.com/jdieter/deltarpm-3.6-0.1.20101230git.fc14.src.rpm
<jdieter> If run with -vv, it will report old rpm, new rpm, and tell us what the
actual first six bytes of what's actually in the rpm
<jdieter> vs the 070701 that it's supposed to be
<jdieter> I don't have an el6 system, so it will have to be rebuilt for releng2
<jdieter> /usr/lib/python2.4/site-packages/createrepo/deltarpms.py needs to modified
as well
<jdieter> The line with "makedeltarpm -v" needs to be changed to
"makedeltarpm -vv"

epel5 scratch build at: 
http://koji.fedoraproject.org/koji/taskinfo?taskID=2694315
(releng02 is rhel5).

If I can get enough +'s I'd be happy to put this in place whenever. 
Otherwise we can wait until next week after the freeze. 

Thoughts? Comments? Other ideas?
