If you're using /usr/bin/g77 as your Fortran compiler (/usr/bin/f77 is
a link to /usr/bin/g77 on our Red Hat Linux system) then -- according
to the TESTED SYSTEMS section in the INSTALL file -- you shouldn't use the
"-Nx400" option.

The above also indicates that you shouldn't use the "-Nx400" option if 
you're using the /usr/bin/g77 Fortran compiler.

It appears that the clock on your system is off.  This might be the
cause of all the problems you experienced.

The above error message is not very helpful in diagnosing the problem (other 
than indicating a severe and fundamental problem).

Let's try starting from scratch.  I suggest doing the following:

    1.  Fix your system's clock.

    2.  Perform steps 2 through 4 near the end of the INSTALL file.

    3.  Set your environment variables as before but ensure that the
        following environment variables have the suggested values:

            ENVIRONMENT VARIABLE        SUGGESTED VALUE
            --------------------        ----------------
            FC                          /usr/bin/g77 (assuming it
                                                      exists; otherwise, use
                                                      /usr/bin/f77 again)
            FFLAGS                      -O -Wno-globals

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

Please let me know if this helps.
