Here's the Ruby I compiled, RMagick (if I used the right path), and  
TextMate's plist extension:

$ file /usr/local/bin/ruby
/usr/local/bin/ruby: Mach-O 64-bit executable x86_64
$ file /usr/local/lib/ruby/gems/1.8/gems/rmagick-2.11.1/ext/RMagick/ 
RMagick2.bundle
/usr/local/lib/ruby/gems/1.8/gems/rmagick-2.11.1/ext/RMagick/ 
RMagick2.bundle: Mach-O 64-bit bundle x86_64
$ file /Applications/TextMate.app/Contents/SharedSupport/Support/lib/ 
osx/plist.bundle
/Applications/TextMate.app/Contents/SharedSupport/Support/lib/osx/ 
plist.bundle: Mach-O universal binary with 3 architectures
/Applications/TextMate.app/Contents/SharedSupport/Support/lib/osx/ 
plist.bundle (for architecture ppc7400):	Mach-O bundle ppc
/Applications/TextMate.app/Contents/SharedSupport/Support/lib/osx/ 
plist.bundle (for architecture i386):	Mach-O bundle i386
/Applications/TextMate.app/Contents/SharedSupport/Support/lib/osx/ 
plist.bundle (for architecture x86_64):	Mach-O 64-bit bundle x86_64

Here's Apple's Ruby for comparison:

$ file /usr/bin/ruby
/usr/bin/ruby: Mach-O universal binary with 3 architectures
/usr/bin/ruby (for architecture x86_64):	Mach-O 64-bit executable x86_64
/usr/bin/ruby (for architecture i386):	Mach-O executable i386
/usr/bin/ruby (for architecture ppc7400):	Mach-O executable ppc
Cakey-Please:~ $ file /Applications/Tex
TextEdit.app/ TextMate.app/

Let me know if I didn't use a good path for RMagick or you want to see  
others.
