Alternative for svn_buildbot.py that does not require twisted?

I am running some Continuous Integration servers. Source repository is hosted on Subversion, and buildbot does the job of compiling and testing after every commit. My trouble is that I had recently to migrate the SVN server to a RedHat5 system. RedHat5 does not distribute twisted, nor zope (essential components of buildbot). Thus, the post-commit hook script of SVN cannot run svn_buildbot.py, the script that triggers the buildbot after each commit.

Does anyone knows about an alternative to the svn_builbot.py script that could trigger the buildbot, but that does not require twisted and zope?

Solution

If you're using buildbot >0.8.2, you can enable the change_hook feature in WebStatus and use post_build_request.py in your SVN post_commit script to trigger the build via an HTTP request.

If you're stuck with an older version of buildbot or cannot enable change_hook for security reasons, then I'd say your options are:

Using SVNpoller to have the buildbot master poll your SVN server for changes
Have your post-commit hook send emails to your buildbot master host, then use SVNCommitEmailMailDirSource.
Compile Twisted from source. I've deployed several buildbot installations on RHEL4 and RHEL5 servers this way without any issues.
