I'm afraid I'm not getting this at all (which could be due to the fact that I don't know unix). I've tried the
# which which
and the
/usr/bin/which
calls, and all I get is command not found errors. Can you tell me more about what the unix command would be to determine if the BSD.pkg file exists?

However, it would be more robust to check for existence command before
you use shell(). The user could have modified the contents of
/usr/bin/. This might be especially common among users of Fink who
install bunches of stuff into /sw/bin. Maybe they leave /usr/bin alone
and just change their path, or maybe they delete stuff? To be really
robust, use which to locate the command in question:
# which which
/usr/bin/which
Unix is so weird! :-)
