Unfortunately, it seems that `sage -sh` doesn't ask the shell to avoid
processing the `.profile` or equivalent. In particular, it can lead to
things like this:
{{{
[EMAIL PROTECTED] ~/new-three-two] $ ./sage -version
Sage Version 3.2.rc0, Release Date: 2008-11-10
[EMAIL PROTECTED] ~/new-three-two] $ ./sage -sh
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!
[EMAIL PROTECTED] ~/new-three-two] $ sage -version
SAGE Version 3.1.4, Release Date: 2008-10-16
[EMAIL PROTECTED] ~/new-three-two] $ which sage
/usr/local/bin/sage
}}}
This comes from the fact that I manually '''prepend''' certain things to
my path in my `.bashrc`. Sadly, this leads to several small, subtle
issues. I've attached a patch which turns several calls to `sage` into
`$SAGE_ROOT/sage`.
However, something more serious is needed. I think that the right approach
is to start the new shell without processing any login files, so that we
know our path is correct. The patch does that.
I'm listing this as a blocker, because it causes such subtle errors, and
because a fix is attached.
