I just built the netCDF 3.5beta package (including the F90 interface) on
our AIX 4.3 system using a particular set of environment variable
settings to inform the configure script about the system.

Try the following:

    1.  Go to the top-level, netCDF source directory.

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

    3.  Ensure that the following environment variables have the
        indicated values:

            CC          /bin/xlc
            FC          /bin/xlf
            F90         /bin/xlf90
            F90FLAGS    -g -qsuffix=f=f90

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

Please let me know if this helps.
