1) Ask BioC to build the package correctly, or
2) Build from the sources yourself, preferably using a static netcdf 
library.

People should not be distributing Mac binary packages with hardcoded 
paths to dependencies not in the R framework: CRAN does not.  In 
particular, /usr/local/lib need administrative privileges to populate.
