buildSRPMfromSCM issue

[Jitesh Shah]

Hi all,
I've been trying out some stuff on my own local koji instance. Recently,
I added a new builder and all the builds using SCMs started to fail
(although, scratch builds on SRPMs work just fine).
 buildSRPMfromSCM fails.

The checkouts go through fine and "make sources" also works. Following
is the tail of the root.log (after "make sources")

The task exits with "FAILED: BuildError: error building srpm, mock
exited with status 2; see root.log for more information"
But, there is nothing suspicious in root.log (yum succeeds, so does
checkout and "make sources" and there are no errors after that too).
state.log and kojid.log also give out nothing. I have enabled full
debugging from kojihub.conf. 

How do I go about solving this issue? From where can I glean more
information about the problem? What does "mock exited with status 2"
mean? and more importantly, why does mock give up abruptly?
