It might be that I my default shell set to zsh. Could you try changing your
shell (using chsh) to zsh and then testing the value of $PATH after doing sage
-sh?
Gee. Ya think? :-}
Here's what I get (again, fresh Terminal window):

zippo% echo $SHELL
zsh
zippo% PATH='.';export PATH
/usr/libexec/path_helper -s
zippo% /usr/libexec/path_helper -s
PATH="/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/opt/X11/bin:/usr/texbin:/usr/X11/bin:.";
export PATH;
zippo%
It seems that when I set my default shell to bash, the $PATH variable is set
correctly in sage -sh.
Doesn't the Sage environment kind of assumes 'bash' is your shell? I've never
thought about it, but a quick check of '$SAGE_ROOT/local/bin' shows that at
least some of the shell files insist on it.
The code in sage-sage seems to indicate support for lots of different
shells. Here is the code to launch the shell from sage -sh. You can
see that not only does sage-sage specifically launch whatever shell the
user defaults to, but also includes configuration for a number of
popular options. If Sage only supports bash as a shell, then shouldn't
SHELL_NAME be set to `which bash` or `/usr/bin/env bash`?
SHELL_NAME=`basename $SHELL`
echo "Bypassing shell configuration files ..."
echo
# We must start a new shell with no .profile or .bashrc files
# processed, so that we know our path is correct
PS1="SAGE_ROOT=${SAGE_ROOT}\n(sage subshell) \h:\W \u\$ "
export PS1
case $SHELL_NAME in
bash)
SHELL_OPTS=" --norc"
;;
csh)
SHELL_OPTS=" -f"
;;
ksh)
SHELL_OPTS=" -p"
;;
sh)
SHELL_OPTS=" --norc"
;;
tcsh)
SHELL_OPTS=" -f"
;;
zsh)
SHELL_OPTS=" -f -d"
;;
*)
echo >&2 "Unknown shell: $SHELL!"
echo >&2 "Exiting Sage."
exit 1
esac
$SHELL_NAME $SHELL_OPTS "$@"
So I guess the problem is narrowed down to: sage -sh doesn't work when
zsh is your default shell on OSX 10.6.6.
Thanks,
Jason
