New description:
On OSX (10.6.6), when starting zsh, the /etc/zshenv file is always
executed (even if the -f option is used to start zsh). This file:
{{{
# system-wide environment settings for zsh(1)
if [ -x /usr/libexec/path_helper ]; then
eval `/usr/libexec/path_helper -s`
fi
}}}
modifies the path to put things like /usr/bin, etc., in at the *start* of
the path (even though the documentation for path_helper says that it
*appends* things to the PATH variable).
So in the end, I get:
{{{
bash-3.2$ ~/sage/sage -sh
Detected SAGE64 flag
Building Sage on OS X in 64-bit mode
Starting subshell with Sage environment variables set.
Be sure to exit when you are done and do not do anything
with other copies of Sage!
Bypassing shell configuration files ...
SAGE_ROOT=/Users/grout/sage
(sage subshell) tiny:~/sage/local/bin grout$ echo $PATH
/usr/bin:/bin:/usr/sbin:/sbin:/usr/local/bin:/usr/local/git/bin:/usr/texbin:/usr/X11/bin:/Users/grout/sage/local/Frameworks/Python.framework/Versions/2.5/bin:/Users/grout/sage:/Users/grout/sage/local/bin:.
SAGE_ROOT=/Users/grout/sage
(sage subshell) tiny:~/sage/local/bin grout$
}}}
Notice that the Sage paths are at the end of the PATH variable. This
causes all sorts of problems when trying to do anything with sage -sh.
