The development version of Numpy (which will become Numpy 2.0) is binary 
incompatible with extension modules compiled with older versions. In your 
case, slycot. You'd need to recompile all extension modules that use the 
Numpy API to fix this. (Also, check which version of numpy you get by 
'import numpy; print numpy.__file__')

I'd suggest to stick with Numpy 1.5.0 or the 1.5.x branch for developing 
stuff in Scipy.
