bundling problem with rubygems 1.3.2

[MarkMT]

Hi

I have run into a problem with bundling gems using 'thor
merb:gem:install' that seems to be related to rubygems 1.3.2. I get
the following error -

-----
$ thor merb:gem:install

Rolling back transaction

Closer investigation shows that merb's tasks/merb.thor/gem_ext.rb
redefines the ::Gem::SpecFetcher fetch method, while rubygems 1.3.2
has modified the interface to SpecFetcher to include an additional
'prerelease' parameter for that method. Rubygems ends up calling the
redefined fetch method from dependency_installer.rb with that extra
parameter and fails because the redefined method does not take the
prerelease parameter.

Just to confirm what I thought was going on... I added the prerelease
parameter to the redefined fetch method in tasks/merb.thor/gem_ext.rb
and then passed that parameter on to 'old_fetch', and everything works
fine.

I am having great success with the workaround posted here: http://github.com/wycats/merb/issues#issue/2

Yeah, that's exactly the fix I made.
