I recently used pkg-install(8) to download Ruby and Ruby gems, then used
gem install irb
to install irb. But when I run irb, my system freezes - I can't ctrl-c my way out of it and I have to reset the virtual machine. The expected irb prompt does not appear. I can run irb -v and get the version number (1.6.2) - but actually running irb causes the aforementioned system freeze. I'm logged in as root. Help!
