I see from the above that you're using both g77(1) and pgf90(1).
This will cause problems because the two compilers have different
argument-passing conventions.  I suggest that you either don't build
the Fortran-90 interface or use pgf90 to build both the Fortran-77 and
Fortran-90 interfaces.

To NOT build the Fortran-90 interface, perform steps 3 through 5
described near the end of the file INSTALL.html and use the following
environment variable settings:

    export FC=/usr/bin/g77
    export FFLAGS="-O -Wno-globals"
    export F90=""               # causes Fortran-90 interface to be ignored
    export CPPFLAGS="-DNDEBUG -Df2cFortran"
    export CC=/usr/bin/gcc
    export CFLAGS="-O"
    export CXX=/usr/bin/g++

Then Perform steps 6 through 9.

To use only the pgf90 Fortran compiler, perform steps 3 through 5
described near the end of the file INSTALL.html and use the following
environment variable settings:

    export FC=/usr/pgi/linux86/bin/pgf90        # for both 77 & 90 interfaces
    export FFLAGS="-O -w"                       # different from above!
    export CPPFLAGS="-DNDEBUG -DpgiFortran"     # different from above!
    export CC=/usr/bin/gcc
    export CFLAGS="-O"
    export CXX=/usr/bin/g++

Then Perform steps 6 through 9.

Please let me know if this helps.
