That's just a warning... I think the actual issue is:

Looks like the ruby that is generated for a gem spec isn't escaping  
the quote character correctly. But it doesn't look like that in my spec:

that looks fine. OK. I have a repro.

% ruby -v -w -rubygems archive-tar-minitar-0.5.1.gemspec ruby 1.8.6  
(2007-09-24 patchlevel 111) [universal-darwin9.0]
# works fine

So that looks like ruby straight up to me...

For someone debugging this... you don't need to install everything....  
You just need the following file:
