From the above, it looks like some environment variables weren't defined
correctly before the configure script was invoked.

Try the following:

    1.  Go to the top-level source directory of the package.

    2.  Perform steps 3 and 4 described near the end of the file
        INSTALL.html

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

            CC=/usr/bin/gcc
            CPPFLAGS='-DNDEBUG -DpgiFortran'
            CFLAGS=-O
            FC=/proj/pgi/linux86/bin/pgf90
            FFLAGS="-O -w"
            CXX=/usr/bin/g++

    4.  Perform steps 6 through 9 described near the end of the file
        INSTALL.html.

Please let me know if this helps.
