Hi,

Some information for those who are interested in using the textmate footnotes plugin described in the PragProgrammer Textmate book, who have updated ruby recently, and who might be having some problems.

I recently updated to Rails 1.2.3 and Ruby 1.8.6 on my intel MacBook Pro. I tried installing the Footnotes plugin for Rails/textmate using the Rails bundle install plugin command and got the following error that started as so:

/usr/local/lib/ruby/1.8/i686-darwin8.7.1/rbconfig.rb:7: ruby lib version (1.8.5) doesn't match executable version (1.8.6) (RuntimeError)

After googling extensively, I found the following explanation and fix on the wincent.com site:

<http://wincent.com/knowledge-base/ Building_and_installing_Ruby_1.8.6_on_Mac_OS_X_Tiger>

It appears that I had previously set the RUBYLIB shell variable in my ~/.bash_profile file to point to:

RUBYLIB="/usr/local/lib/ruby/site_ruby/1.8:/usr/local/lib/ruby/ site_ruby/1.8/i686-darwin8.7.1:/usr/local/lib/ruby/1.8:/usr/local/lib /ruby/1.8/i686-darwin8.7.1" export RUBYLIB

I think I had followed some online recipe a few versions ago to install Ruby and Rails on my computer.

So this entry created a mismatch between the correct lib directory for ruby 1.8.6 and the current version of ruby.

Removing this line from the .bash_profile fixed the plugin error for me.

Hope this helps someone else avoid some frustrations.
