It depends which version of Python your scipy is compiled for and
whether it is compatible with the numpy that veusz is using (1.6.1). If
it matches the python that veusz is using and the ABI is ok, you're
fine. If not, then no (unless you build scipy under a matching
environment). I'm using 2.7 for Windows and Mac OS (using the Python.org
python versions). I'm using a rather old Mac build environment, though,
so it's possible that this will not work.
The trick is to either set the PYTHONPATH environment variable to
include the directory that the scipy distribution is in before running
Veusz (from that shell), or to add a Veusz plugin which just modifies
the Python path, e.g.
import sys
sys.path.append('/Libraries/Frameworks/Python.framework/Versions/2.7/lib/pthon2.7/site-packages')
I could add an option to Veusz to add directories to the PATH if this
would help.
