+The numpy v. 1.8.2 is not able to autodetect the shared libraries created by
+newer versions of ATLAS. Thus if one lets ATLAS create these libraries, she
+has to tell numpy about them.
+
+By default the numpy-legacy script forces numpy to look for the shared, threaded
+ATLAS libraries. If you want to change this behaviour you have the following
+possibilities:
+
+a) Set ATLAS_SHARED to "no". In this case numpy will just look for the
+ apropriate static libraries.
+b) Set ATLAS_THREADS to "no". In this case numpy will be forced to look for
+ the single threaded ATLAS libraries, static or shared depending on the
+ value of ATLAS_SHARED. Otherwise it will look for the threaded ones.
