I installed ruby-1.8.5 from source (with rvm) on mac os x mountain lion but cannot install any gem. I experience the same problem as this guy:

1.8.6 works fine. Do you have any tips?

Is there a reason you have to use such an ancient version? I can't imagine it's supported by well.. anything?

also what version of rubygems is in use: gem version

Yes, there is an old rails project that I need to support. Obviously, the ruby comes with the linux distro and they are unlikely to change it.

$ ruby --version

start with uninstalling rubygems-bundler, it's working only back to ruby 1.8.6 / rubygems 1.3.7:

rvm @global do gem uninstall -ax rubygems-bundler

Aha!!! It worked! 👍 Managed to install rails gems. Thanks a lot! I didn't expect the solution so fast.

Compiled ruby-1.8.5 ended up crashing and throwing malloc errors on login in rails application. Perhaps there is special care needed for this particular version. I compiled it with non-llvm gcc-4.2 on the same machine. 1.8.6 was working fine.

@thehappycoder ruby-1.8.5 is very old, all 1.8 rubies are already end of life, only security fixes will be posted for ruby 1.8.7 for few months. If you really need that old ruby you might want to downgrade operating system to version that was running around when your app was developed. Anyway you might be better with just upgrading app to newer rails. As for the stability error RVM can not help you much more, we try to make old rubies working but you are way behind, I do not think it's possible to easily fix it without hunting down some patches - which is out of RVM scope.
