hi -

gems is great but it kind of hides the code. id like to download
certain gems and customize/build on them.

is there a way to tell a gem to install to a particular directory?

and if an app is built on a gem, to then run it using all the gem
source local in that dir rather than in /usr/local/lib ...

thanks!

The GEM_HOME environment variable is the catch-all way, but there are
also arguments to gem install. RubyGems does not know how to search
multiple directories for gems.

Can you clarify on this?

Reading http://rubygems.org/read/... it seems to support multiple
gem directories.

Am I wrong?

You are right, I am wrong.
