The above message contained the following:

Good.  The C macro "f2cFortran" must be defined on a Linux system.

Strange. "-Df2cFortran" should appear in the above command but doesn't.
Also, "cc" is the compiler rather than "gcc". I suspect that the above
values were put into shell variables rather than into environment
variables.

To assign a value to an environment variable, do one of the following

    export CPPFLAGS=-Df2cFortran

or

    CPPFLAGS=-Df2cFortran
    export CPPFLAGS

or

    setenv CPPFLAGS Df2cFortran

depending on your user shell.

Please try the following:

    1.  Go to the top-level source directory.

    2.  Perform steps 3 and 4 described near the end of the file
    INSTALL.
    
    3. Perform step 5 described near the end of the file INSTALL. Ensure
    that the values are assigned to environment variables and not shell
    variables.

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

Please let me know if this helps.
