My apologies. I hadn't realised that there were now separate dmg  
distributions for Panther and Tiger.

Can you confirm that the ruby installation picked up from the command  
line is your self-installed 1.8.2?

    which ruby
    ruby -v

Can you check that your self-compiled RubyCocoa has definitely been  
installed in /Library/Frameworks? It sounds like perhaps the one from  
the dmg is still there.

Try removing /Library/Frameworks/RubyCocoa.framework altogether and  
rerunning the source install.

The reference to /usr/lib/libruby.1.dylib is probably coming from the  
RubyCocoa framework. You can check with the 'otool -L' command, which  
shows library dependencies (the example below is for the 0.4.2  
Panther dmg):

   otool -L /Library/Frameworks/RubyCocoa.framework/RubyCocoa
../RubyCocoa:
	@executable_path/../Frameworks/RubyCocoa.framework/Versions/A/ 
RubyCocoa (compatibility version 1.0.0, current version 1.0.0)
	/System/Library/Frameworks/Cocoa.framework/Versions/A/Cocoa  
(compatibility version 1.0.0, current version 9.0.0)
	/usr/lib/libruby.1.dylib (compatibility version 1.6.0, current  
version 1.6.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current  
version 71.1.4)
