In Ruby mode, I'd been using cmd-R to run my trivial little scripts,
but recently I came back to them and cmd-R no longer works.  It
simply pops up an HTML window that displays the shell error message,
'/usr/local/bin/ruby: no such file or directory.'  Running scripts
directly from Terminal still works, and my Ruby is in fact in /usr/
local/bin, so I'm basically stumped.  What did I unwittingly change?

perhaps a path problem? might TM_RUBY be set in textmate's preferences to /usr/local/bin/ruby?

cheers,
