This is not a problem.  These are "configuration" "error" that the 
system uses to incorporate platform-specific code.

This is the problem.   The error is telling you that you can't import 
numpy from the directory where numpy was built (the import mechanism 
gets confused between the system-installed numpy and the directory 
structure underneath).

Just exit Python and cd to another directory.   Then numpy should work 
fine.
