While trying to do a svn commit from within TextMate, I get this error:

=== Couldn't find /usr/local/bin

We need Ruby to proceed.

Locations searched:

/Applications/TextMate.app/Contents/SharedSupport/Support/bin/CocoaDialog.app/Contents/MacOS /usr/local/bin/ /usr/local/sbin /bin /sbin /usr/bin /usr/sbin /usr/local/pgsql80/bin /usr/local/pgsql81/bin /usr/local/mysql/bin /sw/bin /Applications/TextMate.app/Contents/SharedSupport/Support/bin ===

A command-line svn commit within the same checkout works perfectly -- so I don't think that this is a svn problem.

Ruby is definitely there; the Rails app I'm developing works fine:

$ which ruby -> /usr/local/bin//ruby

The error is particularly weird, as it clearly is looking at "/usr/local/bin/" when trying to find "/usr/local/bin". What can this mean?

I'm using TM build 1372 (latest), MacOS 10.4.8.

I'm guessing that this is a configuration problem, but I can't figure out what I've got set wrong.

Many thanks in advance for any pointers!
