Comment(by jhpalmieri):
I installed Solaris on a virtual machine on my Mac:
{{{
$ uname -a
SunOS unknown 5.10 Generic_141445-09 i86pc i386 i386pc
}}}
and I get the same results that mhansen reported on t2. Also, the man
page for "which" doesn't discuss error codes. It says, among other things
{{{
NOTES
which is not a shell built-in command; it is the UNIX com-
mand, /usr/bin/which
}}}
I haven't tried to install Sage on this (for one thing, I don't have gcc
installed and I don't know how to get it), but I get similar results in
python: running "call('which lsjdflsjdflkjs', ...)" returns 0, same as
"call('which ls', ...)".
