So you can reproduce the error outside TextMate?

It would appear the REXML parser treats the IO object as more than  
just a pipe (i.e. it tries to seek).

Try instead of using '</tmp/test.log' do: 'cat /tmp/test.log|ruby …',  
see if that changes things. Also try change '2>&1' to '2>/dev/null' in  
the version that fails for you in Terminal.
