I just got a recent installation of Mountain Lion. I installed homebrew and the gcc on dupes to compile proper rubies. Now, with new versions of ruby (1.9.2) I can create and install gemsets and gems.

However, I also need an old environment with ree-1.8.6-20090610. In this environment, when I type gem install whatever, it will not do anything at all.

Here's a trace and some information you may find useful:

➜  dev git:(master) ✗ gem install rails -v 2.1.1 -V

*** LOCAL GEMS ***

rubygems-bundler (1.1.0)
➜  dev git:(master) ✗ rubies

rvm rubies

=> ree-1.8.6-20090610 [ i686 ]
 * ruby-1.9.2-p320 [ x86_64 ]
   ruby-1.9.3-p327 [ x86_64 ]

# => - current

➜  dev git:(master) ✗ gemsets

gemsets for ree-1.8.6-20090610 (found in /Users/bernatrafalesimulet/.rvm/gems/ree-1.8.6-20090610)
=> (default)

The same happens when I try to install any other gem.

make sure you use ruby first:

rvm use ree-1.8.6-20090610

this is required when PATH get's modified after RVM was sourced and loaded ruby.

you can confirm that ruby is properly loaded by comparing beginning of PATH with GEM_PATH.

also make sure there are no extra settings for rubygems in ~/.gemrc, rvm has a test for this:

rvm get head

and make sure to read the output - if there were any extra settings in ~/.gemrc you should install all gems all over again.
