Question

I\'m running 1.9.2 with rails 3.

I\'m using rvm.

I did:

sudo gem install ruby-gem

and got:

Building native exte         


        

Answer 1

Installing gem ruby-debug-base19x also failed due to connection problems by using cntlm proxy and "--with-ruby-include" didn't worked for me. Installing the gem without a proxy worked smoothly.
