The above environment variable settings probably won't work.

Please try the following:

    1.  Go to the top-level source directory.

    2.  Perform steps 3 and 4 described at

    3.  Set the following environment variables to the indicated values:

            CC=gcc
            CPPFLAGS='-DNDEBUG -DpgiFortran'    # note spelling
            CFLAGS=-O
            FC=pgf90
            FFLAGS='-O -w'
            CXX=g++

    4.  Perform steps 6 through 9 described at
