Null byte error trying to install ZenTest

Rails
1

I’ve got a fresh Ruby/Rails install (compiled Ruby from scratch,
installed latest Rubygems etc) and I have had no problems installing any
gems except for when I hit ZenTest. I keep getting the following:

matthew-williamss-macbook:1.8 matthewwilliams$ sudo gem install ZenTest

Any thoughts? It’s a fresh install, I’ve done gem update --system to
make sure I"m up to snuff but no such luck…

Any help would be appreciated, I need to get autotest running! Thanks!
