No, there is a "?" for when the builder was created, and nothing else in
that column.  When I click the changes link, it just lists the single
p4source I configured, with the information I configured for it.
 
In the log on the master, all I have is " P4Poller: starting at change 149"
again implying that it's at least able to read from perforce, it just
doesn't seem to care about changes.

Ah, my apologies for not being clear, the gobject issue is on all platforms,
but based on what you said here that is expected.  I'll wrestle with the
pygtk install to try and get that working.  :)

Ah!  Okay, I was wondering about this, and must have missed it in the docs.
I kept reading about forcing a build, but never could find it on the web
interface.

I just did a ping of the builder with the new options available to me on the
web interface, and that was a success.  I then attempted to force a build,
and get this in my log:

2008-10-10 07:26:44-0700 [HTTPChannel,0,192.168.6.3] web forcebuild of
builder 'Installer Framework', branch='None', revision='149'
2008-10-10 07:26:44-0700 [HTTPChannel,0,192.168.6.3] maybeStartBuild
<Builder 'Installer Framework' at 34381536>:
[<buildbot.process.base.BuildRequest instance at 0x20c9c10>] [<SlaveBuilder
builder=Installer Framework slave=macinstall>]
2008-10-10 07:26:45-0700 [HTTPChannel,0,192.168.6.3] <Builder 'Installer
Framework' at 34381536>: want to start build, but we don't have a remote


I googled for the 'want to start build, but we don't have a remote' error.
I see a couple other people with the issue.  It seemed the consensus was
that restarting the slave would allow it to continue, and this worked.  I
then ran into a problem where the source sync on the slave failed unless I
added a perforce client specification name (which according to the docs is
optional).  

I then ran into this when it is attempting to do the actual sync:

remoteFailed: [Failure instance: Traceback from remote host -- Traceback

The odd thing is, I figured I could just create the 'build' directory for
it, but it (rightly so) blows out the macbuilds directory before every
build.  Any ideas what I could be missing?  It seems there must be some
simple I'm missing.

Thanks!
