postgresql - How do I get "gem install" to work on OS X Lion with Ruby 1.8.7 without seg faulting?

I am novice rails/terminal user and just did a fresh Lion install + Xcode after that.

Installed RVM but when I execute "gem install [any gem]" in terminal, I get this error:

/Users/[my user]/.rvm/rubies/ruby-1.8.7-p352/lib/ruby/1.8/timeout.rb:60: [BUG] Segmentation fault
ruby 1.8.7 (2011-06-30 patchlevel 352) [i686-darwin11.0.0]
Abort trap: 6

Can anyone help, please?

PS. I am using - and in the project I am working on, I must use ruby v1.8.7.

Make sure your rvm is up to date: rvm get latest

And then run this: rvm uninstall 1.8.7 && CC=/usr/bin/gcc-4.2 rvm install 1.8.7

Basically you must tell rvm which gcc compiler to use (CC=/usr/bin/gcc-4.2)

Then you should be able to install the pg gem as normal.
