Comment(by GeorgSWeber):
Sorry,
I do know how to properly attach patches to trac, of course. But I don't
know either how soon I get around to find enough time to do so. And the
one-liner in the comment above (add to the extcode hg repo, or in a "live
install" to the file "start-sage-sh" under /Applications/Sage-
xyz/Contents/Resources/sage) was simply too tempting to be kept entirely
unposted.
The story: In this "start-sage.sh" when called in a fresh install, the
directory "$DOT_SAGE/sage_notebook.sagenb" is checked for existence and
will not exist. Then (and only then) some different means to start up the
Notebook server is chosen, by some call to Terminal. Under OS X Lion, it
seems this way leads to some strange re-sorting of the entries in PATH
variable (which had been properly set before in "start-sage.sh"). As a
result, /usr/bin/python is called instead of Sage's python --- hence the
failures to find "_socket" and "IPython"!
The one line added cares for when sage-env is sourced a second time (which
is the case), the environment variables are set again (which wouldn't be
done if SAGE_ENV is kept set to "1"), including PATH now being what we
want.
Once the Notebook server has started once up (where the user has to set in
the terminal the admin password and such), the one directory checked for
exists, and the a different codepath is taken (which works without
changes).
