The above indicates that you need to tell the C compiler what
argument-passing conventions to use for C functions that are called
from Fortran routines. Because you're using g77(1), this is done by
ensuring that the environment variable CPPFLAGS contains the string
"-Df2cFortran".

Try the following:

    1.  Go to the top-level source directory.

    2.  Perform steps 3 through 5 described near the end of the file
        INSTALL.

    3.  Ensure that the environment variable CPPFLAGS contains the
        string "-Df2cFortran" (without the quotes) e.g.,

            export CPPFLAGS=-Df2cFortran

        or

            setenv CPPFLAGS -Df2cFortran

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

Please let me know if this helps.
