I have a question regarding sage on macosx. My problem is that the precompiled binary package of sage doesn't see my python modules installed through macports. I mean sage is working without porblem, but when I try to attach a script which use a module (e.g. scitools) I got : Applications/Sage-4.7.2-OSX-64bit-10.6.app/Contents/Resources/sage/local/lib/python2.6/site-packages/sage/misc/preparser.pyc in load(filename, globals, attach) 1629 1630 if fpath.endswith('.py'): -> 1631 execfile(fpath, globals) 1632 elif fpath.endswith('.sage'): 1633 exec(preparse_file(open(fpath).read()) + "\n", globals) Volumes/Henry/Script_py/plot/example.py in <module>() 2 import time, glob, os 3 4 # clean up old frames: 5 for name in glob.glob('tmp_*.eps'): 6 os.remove(name)

ImportError: No module named scitools.all

But if I try to execute without Sage, I have no problem with loading the modules.

This is by design, in fact. Sage uses (and builds) its own Python. So you shouldn't expect this.

However, my understanding is that

sage -sh
easy_install scitools

should work, where the Sage Python is invoked in the Sage subshell. For some reason that didn't work for me, but

sage -sh
easy_install brian

did, and I could use it in Sage, so the problem doesn't seem to be easy_install.

related: I don't know how to install (for Sage) python modules which *don't* use the easy_install approach. For example, http://www.shogun-toolbox.org provides a machine-learning C library with interfaces for python and other languages; I can install it and its python interface with macports, or by hand, but not with easy_install.
