Malloc.h could be seen as a bug in pygsl: it's a non-standard header,  
you should include stdlib.h.

The Numeric problem is more subtle: The standard Python file layout  
doesn't cater for the fact that its include directory is non-writable  
by mere sysadmins. Apple worked around this for site-packages by making  
it a symlink into /Library/Python/2.3, but a similar workaround wasn't  
done for the Python include and bin directories (where the workaround  
would also have been more difficult).

A workaround that is theoretically a bad idea (but in practice works:-)  
is to make  
/System/Library/Frameworks/Python.framework/Versions/2.3/include/ 
python2.3 writable to yourself.
