I had a similar error a little while ago, and I got around it by recompiling the problem package with the new numpy/scipy already installed. I also had a possibly related problem with getting bus errors on import that went away after I recompiled the packages except in the case of Matplotlib, which I had to revert to v.98.

Upgrading my timeseries to the latest: M:\src\timeseries>svn up Fetching external item into 'scikits\timeseries\doc\sphinxext' External at revision 7375. At revision 2216.
