Hi,
Currently with trunk, gem unpack fails if you pass it a gem that isn't
in the default gems repository, but another repository.
It is the case in Mac OS X 10.5, where there are 2 repositories, but
all pre-installed gems being in the non-default one.
$ ruby -r rubygems -e "p Gem.dir, Gem.path"
"/Library/Ruby/Gems/1.8"
["/System/Library/Frameworks/Ruby.framework/Versions/1.8/usr/lib/ruby/gems/1.8",
"/Library/Ruby/Gems/1.8"]
$ gem unpack termios
ERROR: While executing gem ... (Gem::Exception)
Cannot load gem at
[/Library/Ruby/Gems/1.8/cache/termios-0.9.4.gem] in /Volumes/Data
The following patch fixes the problem.
$ gem unpack termios
Unpacked gem: '/Volumes/Data/termios-0.9.4'
