Howdy Mike!

This is a consequence of using shared libraries. See our FAQ for a full 
explanation.
http://www.unidata.ucar.edu/software/netcdf/docs/faq.html#Shared%20Libraries

You can either set environmental variable LD_LIBRARY_PATH to point at the 
directory where you installed the netCDF library, or else you can do a make 
uninstall and start over, this time using --disable-shared to the configure.

Good luck,

Ed
