 Various reports around the web indicate that netcdf, on the mac, can fail
 with an infamous '''Error dyld: Symbol not found:
 _H5P_CLS_FILE_ACCESS_g''' error. According to the Unidata FAQ entry
 [http://www.unidata.ucar.edu/software/netcdf/docs/known_problems.html#o_problem_mac
 http://www.unidata.ucar.edu/software/netcdf/docs/known_problems.html#o_problem_mac]
 the "solution" is to compile netcdf with '''-g''' rather than '''-O2'''
 gcc options.

 After much tinkering, I've discovered that this advice is incorrect, and
 have emailed ''support-netcdf @ unidata.ucar.edu'' the correct solution,
 below, asking them to update their web page.

 The problem is that their configure scripts fail to add an '''-lhdf5''' to
 the autotools-generated Makefile. The iconv, szlib, and zilb dylibs all
 get added, but somehow hdf5 gets left out.

 Thankfully, the simple fix is to add the library manually through the
 environment variables.
