Hi,

I’m attempting to install Rails through RubyGems on OS X 10.4.10, but  
whenever I use “sudo gem instsll rails --include-dependencies” it gives  
me this error:

ERROR: While executing gem … (URI::InvalidURIError)  
can not set user with registry or opaque

Can anyone tell me what might be causing this error or how to fix it?  
Or if not, if there’s another way for me to get Rails and Mongrel?  
Thanks.

If you have a proxy setting like [bogus.org:911](http://bogus.org:911) you need to change it to
