Set up an environmental variable TM_RUBY to point to the version you  
want to use.  See TextMate manual for details on this.

Alternatively include the directory holding the new ruby in your PATH  
before the /usr/bin where the Apple Ruby lives.

How you do this depends on which shell you are using.  For tcsh add  
something similar to your .cshrc file in your home directory:

set path = (/opt/local/bin $path)

where opt/local/bin is where DarwinPorts has put Ruby (not sure if  
this is the correct place - do ls to check).  You may need to restart  
TextMate for it to see this change.
