I think you may have been right the first time.
The Numeric module always seems to pickle its 
matrices in a binary format, whichever pickler
is used. I suspect it's just dumping whatever
is in memory, so as you say, it's non-portable.

If you want a portable format, you may have to
convert the Numeric matrices to standard Python
lists or tuples before pickling.
