[SciPy-dev] Problems with freetype (CVS).

This happened to me also.  It looks like the ft_spec.pyc and build_ft.pyc files left over in the scipy/Lib_chaco/freetype directory after the code re-organization are the culprits.  The new .py files for these guys have been moved down into the src directory.  Just delete these old files, and then rebuild.  All should work fine...

thanks for catching this,
eric
