Here's another possibility.  Try setting the environment variable mentioned here
before running configure:

  
http://www.unidata.ucar.edu/software/netcdf/docs/known_problems.html#intel-fortran-macosx

Namely "lt_cv_ld_force_load=no".  I'm not sure why it would be needed, but it's 
solved
some problems compiling with ifort on MacOS-X previously ...
