Youch. Thanks for letting me know!

Well, py-netcdf4 depends on netcdf so it should get its compiler
dependencies that way. Setting configure.compiler is a not really
possible since netcdf could depend on hdf5 which depends on mpi, so
there'd be be no way of knowing if we should set it to clang / gcc or
mpicc :-/
