PS There's some mention of Ryan's lsodar.pyf in the trunk of scipy SVN, as per

projects.scipy.org/scipy/scipy/browser/trunk/scipy/integrate/setup.py?rev=4763

but I don't know if it's still there. If it is, is the associated pyd
now shipped with Scipy? I haven't installed a new version for months.
