I have something working. It's ugly.

You will need:

The latest snapshot of Test::Harness 2.99:
   http://svn.hexten.net/tapx/trunk/

Test::More::Diagnostic:
   http://svn.hexten.net/tapx/Test-More-Diagnostic/trunk/

TAP::Formatter::TextMate
   http://svn.hexten.net/tapx/TAP-Formatter-TextMate/trunk/

Set up a TextMate command that looks something like this:

   test=''
   opts='-rb'
   if [ ${TM_FILEPATH:(-2)} == '.t' ] ; then
       test=$TM_FILEPATH
       opts='-b'
   fi
   cd $TM_PROJECT_DIRECTORY && prove --merge --formatter  
TAP::Formatter::TextMate $opts $test

and in your tests:

   use Test::More;
   use Test::More::Diagnostic;
   plan tests => 1000;

You'll get test output with any test failures linked to the right  
line the test.

It's a hasty lashup. Improvements welcome :)
