recompiled ruby - now "mach-o, but wrong architecture" macvim error

Question

I am recieving the following error when trying to use MacVim:

~$mvim index.php 
dyld: Library not loaded: /usr/lib/libruby.1.dylib
  Referenced from: /Applications/MacVim.app/Contents/MacOS/Vim
  Reason: no suitable image found.  Did find:
    /usr/lib/libruby.1.dylib: mach-o, but wrong architecture
    /usr/lib/libruby.1.dylib: mach-o, but wrong architecture
Trace/BPT trap

Also of interest:

~$/usr/lib/libruby.(tab)
libruby.1.dylib  libruby.dylib

I recompiled ruby as stated here: hivelogic ruby setup. I use macvim heavily, and use gem based plugins such as fuzzyfinder_textmate.
