This is very interesting.  I just found the same error, when I tried to
install rubygems using darwinports.  I made sure to synch up to the
darwinports tree before I tried installing

rb-rubygems

For those interested, the first line in each of those 3 files read:


#!/Users/arthur8/darwinports/dports/ruby/rb-rubygems/work/destroot/opt/local/bin/ruby

rather than the appropriate path:

#!/opt/local/bin/ruby

I also editted each of thosee files to alter the ruby executable path,
but a then different problem appeared.  Typing

gem

threw an exception:


/opt/local/lib/ruby/1.8/fileutils.rb:181:in `mkdir': Permission denied

Evidently, the rb-rubygems darwinports fails to create the doc
directory in

/opt/local/lib/ruby/gems/1.8

Manually creating that doc directory seems to get gem working.

The version of rb-rubygems in darwinports is 0.8.1, but rubygems is now
at 0.8.3.  Perhaps the lateset version of rubygems with these fixes in
place can be put into darwinports?
