error in CULA interface

Hi,
I am trying to use to CULA interface with CUDA fortran for linear algebra libraries

i am not able to compile the CULA interfaced fortran file. I am just using the example interface file given by pggroup.
Can anybody help me to fix this?


command:
pgfortran -mp -L/home/ssk87/cula/lib64 -rpath /home/ssk87/cula/lib64 -I//home/ssk87/cula/include CULA_TEST.cuf -llapack -lcula_pgfortran

Error:

This looks like a basic linker problem. The liblapack included with the PGI distribution does not include the BLAS entries; you’ll have to add ‘-lblas’ to your link line. CULA is not a drop-in replacement for lapack or the blas.
