Comment(by jhpalmieri):
I have one idea how to fix this, but it doesn't seem ideal: first, change
the SHELL_OPTS for zsh to " -d". Then create a .zshrc file, say in
SAGE_ROOT/local/bin, containing
{{{
export PATH=$SAGE_ROOT:$SAGE_LOCAL/bin:$PATH
}}}
and then tell zsh to read this file when starting up. The following patch
to sage-sage does it, and also fixes the prompt:
{{{

I think that setting the prompt for csh and tcsh might require a similar
trick, since their prompt doesn't seem to be governed by an environment
variable the same way.
