[TxMt] Set the SHELL to use for bundle commands

Hi

I'm trying to teach TM to play nicely with Gentoo Prefix. (That's Gentoo Linux installed in a subdir such as /Gentoo which comes with it's own compiler, but runs on the Darwin kernel. Very handy for Ruby development.) Even if I set all environment vars explicitly in TM, I have hickups here and there. I'd like to tell TM to use the bash from Gentoo Prefix /Gentoo/bin/bash instead of the one coming with Mac OS X. Is there a way to do that?

Even when doing a "/Gentoo/bin/bash -l" in bash_init.sh and then dump the environment in a bundle command, I still see "SHELL = /bin/bash" there. Is bash_init.sh read for scripts run from a bundle command at all?

Cheers and thanks, -svoop
