chain-build broken with the lastest code

[Nathan Blackham]

I just updated to the latest code in the repo and it appears that
chain-builds are now broken.  When I have specified more than one URL to
build before doing a "waitrepo" it will only build the first one and then
move on to the wait repo step without trying to build the rest of the
packages specified.

Anyone else seen this?  Any ideas on where it might be broken?
