So far I have been unable to get rails working on a 10.5.6 OS X
installation. Every 'rails' command ends with the following error:
RubyGem version error: ruby-openid(2.1.7 not ~> 2.0.0)
I tried uninstalling and then re-installing ruby-openid, but that
doesn't help. Working with rails on Windows and Linux machines was
never a problem, but this one has me baffled.
