I figured the include directories in site.cfg were greedy, so I
changed the order to
library_dirs = /usr/local/lib:/usr/lib:/home/skipper/atlas/lib
include_dirs = /home/skipper/atlas/include:/usr/local/include:/usr/include:/usr/include/suitesparse
but I get the same import error in numpy.
The correct include directory is listed in the build log, but I'm
wondering why it says atlas 3.8.3 when I installed 3.8.0
New build log attached.
