Well - the question was about the LGPL.  My reading of the license:

http://www.gnu.org/licenses/lgpl.html

is that (under section 6) you are allowed to distribute an LGPL
library with non-derived code that links to it, as long as your own
license terms 'permit modification of [your] work for the customer's
own use and reverse engineering for debugging such modifications', and
that you provide (section 6a) the source code to the code linking to
the library and the library itself.

If I read that correctly, it seems to me that an LGPL library can be
included with SciPy without SciPy needing to change its own license.

Best,

Matthew
