Setting the environment variable

  lt_cv_ld_force_load=no

(an internal configure variable from libtool) before invoking the
configure script.  This workaround successfully builds netCDF version
4.1.3 with the Intel ifort Fortran compiler (ifort version 12.1, but
perhaps also earlier versions) on Mac OS X 10.7 (Lion and perhaps
earlier versions).

More details are here:

Thanks to new Unidata staff member Sean Arms for pointing out this
solution and to Dave Allured (NOAA/PSD/CIRES) for providing another
work-around that pointed the way.
