RectBivariateSpline is defined in scipy/interpolate/fitpack2.py, where all
I can find is a call to dfitpack.regrid_smth. However, in the FITPACK
library, I cannot find a function by that name -- and I couldn't really
find the source code to dfitpack.so to check how FITPACK actually gets
called ...

Any ideas?
