Please try the new 4.1.2-beta1 release of the netCDF C/Fortran
libraries. The 4.1.2 release contains bug fixes and internal
refactoring.
Users of parallel I/O with netCDF-4 please note: starting with the
4.1.2-beta1 release the parallel I/O functions are prototyped in
netcdf_par.h, not netcdf.h. You must include netcdf_par.h BEFORE
netcdf.h to use parallel I/O with netCDF-4.
This release contains the following:
* Modified opendap constraint parser to be more compatible with a
java version of the parser.
* Modified ncgen to utilize iterators internally; should be no user
visible effect.
* An internal refactoring of the C library allows for easier
maintainance and extension of the netCDF library. This
restructuring of the library code is invisible to the
end-user. Two new directories have been added to the netCDF build:
libdispatch, which decides whether to call a netcdf classic,
netcdf-4, or opendap version of each function in the API, and
liblib, where, depending on the configure choices, the final
netCDF library is assembled from convenience libraries created in
other directories.
* Fix for make bug which caused documentation to be unnecessarily
rebuilt after make clean.
* Fix for bug in accessing a multidimensional variable with more
than 4 billion values on a 32-bit platform.
* Fix for memory performance problems in parallel I/O. The automatic
use of HDF5 buffers in parallel programs with netCDF-4 resulted in
large memory use.
* Fix netCDF-4 bug caused when doing enddef/redef and then defining
coordinate variable out of order.
* Refactoring of netCDF-4 internals to reduce memory use and end
dependence on size of NC_MAX_DIMS and NC_MAX_NAME.
* Fix "ncdump -c" bug identifying coordinate variables in groups.
* Fix bug in libsrc/posixio.c when providing sizehint larger than
default, which then doesn't get used (thanks to Harald Anlauf).
* The netCDF C/Fortran/C++ source code has been moved to Unidata's
subversion server. Interested users can now examine the netCDF
code in its full glory and gory internals at
http://sub.unidata.ucar.edu/netcdf.
* Documentation improvements, especially relating to creating
netCDF-4 compatible files with HDF5 only.

It looks like the C lib refactoring may be a problem on OSX..ld: duplicate symbol _nc_inq_att in .libs/libnetcdf.lax/libncdap4.a/att.o and .libs/libnetcdf.lax/libdispatch.a/att.o
