The libtool command should be linking to just "libexpat.so", not 
"usr/lib/libexpat.so", as then the appropriate 64-bit library
would be found in /usr/lib64, which is in the default path for 64-bit Linux 
platforms.  You might try the latest snapshot for
netCDF 4.1.3 to see if the problem is fixed in that version:

  ftp://ftp.unidata.ucar.edu/pub/netcdf/snapshot/netcdf-4-daily.tar.gz

because our nightly test shows this is building with udunits OK on a Linux RHEL 
system:
