Re: [ferret_users] Ferret in Mac 10.8 (Mountain Lion) => Works!

Karl, Billy,

Given that Billy was trying to install in /usr/local it's likely that he
was running as root under bash when he set up Ferret rather than his
normal tcsh. Maybe Finstall should ask for the default shell? The other
explanation would be the environment variable SHELL isn't set (this
would be odd).
