Mac OS X defaults to /bin/bash but things get weird because sh on mac is also bash. Funnily enough a complete separate binary and not a symlink. Anyway, this means things written for the Mac may not work directly on FreeBSD. What I mean is that bash3 syntax is not going to be backwardly compatible with sh. If you wish to retain the bashiness of the scripts then the easiest option would be to install the bash (3.x) port and use env to invoke the appropriate shell on each system.
