Thanks Roland! 

Using the openblas thorn didn't work for me, but setting lapack and blas to BUILD did work to get rid of the lapack fortran warning I was getting. I also figured out what I was doing wrong with the GW150914 test. Maybe it would have run fine with that warning, but I'm glad everything seems to be working now in any case. 

Next I will be trying to set it up on a different cluster, so I might be back with more questions soon if I get stuck on that one too.

Thanks again,

Rhiannon.
