rdoc

Hey all, I've recently installed RDoc version (2.4.3) through Ruby gems to replace the one shipped with Mac OS X (version 1.0.1). Unfortunately, I can still only use RDoc 1.0.1 when I call run "rdoc" at the command line. rdoc -v returns:

RDoc V1.0.1 - 20041108

I tried amending the $PATH variable to point the first entry to the RDoc 2.4.3 folder but no luck. I couldn't find anything about this online either, so I thought I'd ask here.

Cheers!

Update:

Running "gem list -d --version 1.0.1 rdoc" returns:

*** LOCAL GEMS ***

rdoc (2.4.3)
    Authors: Eric Hodel, Dave Thomas, Phil Hagelberg, Tony Strauss
    Rubyforge: http://rubyforge.org/projects/rdoc
    Homepage: http://rdoc.rubyforge.org
    Installed at: /usr/local/lib/ruby/gems/1.8

    RDoc is an application that produces documentation for one or more
    Ruby source files

Therefore, it's definitely the Mac OSX version of RDoc that's interfering with the Gems version.

Update 2:

I found out, using:

`bash --debugger rdoc`

that the old version of RDoc was in /opt/local/bin. I deleted it and added my gems directory to my $PATH

`export PATH=/usr/local/lib/ruby/gems/1.8/gems/`

I now have a fresh working copy of the latest RDoc!
