gem requires not working

[Steve Ross]

I feel stupid about this, but I just did a fresh install of 1.8.5 from
MacPorts, installed a fresh rubygems, installed all my gems, and simple
code like this fails:

require 'redcloth'

Error message:

lacosta:~/nitro/tracker sxross$ ruby bug.rb
bug.rb:1:in `require': no such file to load -- redcloth (LoadError)

The odd thing is that any requires *inside a Rails app* seem to find the
gems just fine. I assume that's because Rails munges the load paths.

Any help is appreciated.

Actually it's because of config/boot.rb in your Rails app. Specifically:
require 'rubygems'

If your code was working before, and didn't need this, then it's
possible that you had had RUBYOPT set.

You're right, it's the explicit:

require 'rubygems'

Shouldn't this be implicit? Or am I misremembering...

Thanks

You are misremembering.

Some people set RUBYOPT=-rubygems (or is it RUBY_OPT?)

It's not a standard part of Ruby, it's an external library, so it should
remain explicit. If you're using it on your system you most likely do
want to set RUBYOPT="-r rubygems".
