Yes, it may be that you didn't set the F90FLAGS environment variable
before building, as in the working examples of building for AIX in the
INSTALL.html document that was included with the source distribution
or at:

  http://www.unidata.ucar.edu/packages/netcdf/INSTALL.html#aix

If you remove the "config.cache" file, set the F90FLAGS variable to
"-qsuffix=f=f90", and rerun the configure script, it may find the
xlf90 compiler works.  If not, take a look at the associated error
message in the "config.log" file (not the "configure.log" file) to see
why the simple Fortran90 test program can't be successfully compiled.
It works fine on our AIX 4.3 system.
