I need to retrieve and unpack a large number of gems, without
either (a) affecting my local gem installation or (b) getting
involved with dependencies. "gem fetch" will retrieve random
gems, but "gem unpack" is a bit more picky.
According to http://docs.rubygems.org/read/chapter/10#page34:
You can only unpack gems that you have installed, ...
I can hack the gem command to get the results I want, but it
seems like there should be a way to do this. Clues, anyone?

Do it like this
cd /tmp
GEM_HOME=$PWD GEM_PATH=$PWD gem install PACKAGE
So look in cache directory. All gem is there.
Just do gem unpack GEM and done !
System is protected ! You can do it as user to be sure of that.

Oh no--you can unpack arbitrary gems [I think that's the only ones you
can].
gem fetch gem_name
gem unpack gem_name.version.gem
Cheers.

There's probably a feature request for that, but I've not bothered to implement it.
It would be a nice feature to have, though, so I welcome a patch if you have more time than me.

Won't that still install bin stuff? For example, gem install rake.

That is really close, but it gets a nastygram:
$ gem unpack rails.2.3.2.gem
ERROR: While executing gem ... (Gem::Exception)
Cannot load gem at [rails.2.3.2.gem] in .../rails
However, this seems to work just fine:
$ gem unpack rails-2.3.2.gem
Unpacked gem: '.../rails/rails-2.3.2'
Thanks!

You can do like this :
gem fetch rake
ls rake*.gem
et pour l'unpack
gem unpack rake*.gem
=> nothing install
