It sounds like the directory you put it under should be okay, but 
perhaps you screwed up something else in your NumPy installation (e.g. 
you are missing other header files, or....).  Whenever you find yourself 
copying header files around manually, you are usually making a 
mistake...it would really be much better if you figure out what package 
in your distro is supposed to include the header files.

You can look in the config.log file generated by the configure script in 
order to find the exact compiler error message that caused #include 
<numpy/arrayobject.h> to fail.
