What does 'which ruby' say?
How about 'sudo which ruby' ?
How about 'sudo which gem' ?

Make sure /opt/local/bin comes before /usr/bin in your $PATH.

Yes. The "ruby" port appears to be pegged at 1.8.7.

> Help, please.

Worst case: The ruby?? ports each install their executable binaries in 
/opt/local/bin, so if for some reason reinstalling a recent ruby port 
and 'port select'ing it doesn't work, you can try:

sudo /opt/local/bin/gem3.0 install coltrane

Or whatever version of ruby you choose.
