Building native extensions.  This could take a while...
ERROR:  Error installing ruby-debug:

Gem files will remain installed in /Library/Ruby/Gems/1.8/gems/linecache-0.43 for inspection.

Do you have the OS X Developer tools installed? They are on the Leopard DVD in additional packages, if I remember correctly.

They contain the compiler the gem build process needs.

Thanks, I managed to install the Xcode Tools package from the Leopard DVD under Optional Installs / Xcode Tools. After that I was able to successfully install ruby debugger from my terminal window running sudo gem install ruby-debug and then the rubymine debug ide.
