[Distutils] Buildbot throwing a gear after default setup?

[ssteinerX@gmail.com]

I've just downloaded and configured the Distribute buildbot and it  
appears that a dependency is missing somewhere.  I get this (just the  
errors excerpted).

Just wanted to capture this before I figure out what needs to be done...

test_make_tarball

'requires zlib'

test_tarfile_vs_tar
