[TxMt] Mate command broken

Originally when I installed Textmate it offered to put in the link for the "mate" command which I chose to do. The mate command worked from terminal until the next day when I fired up my computer and suddenly it stopped working. So I went into the "Help" menu, "Terminal "Usage" option and clicked the "Create Link" button for /opt/local/bin, it gives me an error "Couldn't create link: /opt/local/bin/mate filed ... bad address". If it use any of the other paths I get an error the the operation is not permitted.

Not sure what to do. Isn't mate just a symbolic link to the actual textmate.app in applications?

Thanks for nay help on this.
