We should ensure that Linux binary distributions are correctly
labelled, e.g. "RedHat 6.2 i386 Linux", not just "Linux". A package
with as many dependencies as GRASS is unlikely to work fully on a
distribution which differs from the one on which it was compiled.

This is arguably an installation bug. The fix is to ensure that SHELL
gets set to something which programs will recognise, e.g. by adding
something like:

	if [ "$SHELL" = /bin/msh ] ; then
		SHELL=/bin/bash
		export SHELL
	fi

to /etc/profile. I suspect that GRASS isn't the only program which
does case matching on $SHELL.

OTOH, GRASS should work with unknown shells. The main case statement
has a default case; does anyone know what's wrong with it?

You don't need to duplicate the bash case; you can just use "|", e.g.

	bash|msh)
