[Numpy-discussion] numpy and the ACML

I've tried building CBLAS, which seems to run properly by itself, but  
numpy is still having difficulty.  I've got the following in my  
site.cfg:

[blas_opt]
library_dirs = /usr/local/nonsystem/simpson/CBLAS/lib/LINUX:/usr/local/ 
nonsystem/simpson/acml4.2.0/gfortran64/lib
include_dirs = /usr/local/nonsystem/simpson/CBLAS/include:/usr/local/ 
nonsystem/simpson/acml4.2.0/gfortran64/include
libraries = cblas, acml

[lapack_opt]
library_dirs = /usr/local/nonsystem/simpson/CBLAS/lib/LINUX:/usr/local/ 
nonsystem/simpson/acml4.2.0/gfortran64/lib
include_dirs = /usr/local/nonsystem/simpson/CBLAS/include:/usr/local/ 
nonsystem/simpson/acml4.2.0/gfortran64/include
libraries = cblas, acml

I also created a symbolic link in /usr/local/nonsystem/simpson/CBLAS/ 
lib/LINUX, from cblas_LINUX.a to libcblas.a.


Is there an easier way to check if numpy is locating the libs other  
than doing python setup.py build, and looking at the output?
