Are you using the latest HDF5 release?

Also, please try upgrading to the netCDF daily snapshot for dramatically
improved parallel I/O performance, and also much improved performance
with large data files, whether accessed in parallel or sequentially.

If you can't get it working, create a small C program that demonstrates
the problem and email it to me, and I will see if I can spot your
problem.

Thanks,

Try without --with-pic and also without --enable-c-only. (For faster
builds you can use --disable-examples --disable-utilities
--disable-fortran --disable-cxx).

Thanks,
