NO Thanks for everyone's help. Unfortunately, still no success. So I took the alternate route suggested in section A.3.1.5 of R-admin, and just created a symbolic link from libRblas.so to .../libmkl_gf_lp64.so. I can still multiply 2 matrices together in R, so it looks like this is working. Can you propose any other test to be sure?
Should I make a similar link for LAPACK? I'm still perplexed as to why configure couldn't find the MKL BLAS, but I suppose any solution that works is a good one. Thanks again.
