  ... [config.log with error messages]

Error messages in "config.log" are not necessarily indicative of a
problem, since the "configure" script may need to try things that
generate errors in order to deduce and correctly configure the
compilation environment.

The immediate cause of this error was a missing "-lnsl" flag on the CC
line above that linked with the libraries.  This "-lnsl" flag should
have been included in the cxx/Makefile when it was generated by the
"configure" script.  The fact that it's not there seems to indicate that
the "configure" script hasn't been run on this platform yet, or is using
incorrect information it finds in the cache file "config.cache".

It looks like you're trying to run "make" without first running "make
clean" and "configure".  This would work OK if you had previously run
the "configure" script on this system, but if what you have is left over
from a previous run of "configure" on a different system, this won't
work.  The INSTALL file gives the details of what's needed to build
netCDF, but if you're starting from a previously built source tree, you
should first run "make clean" (to get rid of all the old object files)
and "rm config.cache" to make sure the "configure" script starts with a
clean slate and not some previously generated but incorrect information
about the plat-from.

Then run "configure", possibly with a "--prefix=whatever" argument to
specify where you want things to be installed, if the default is not
appropriate.

Then run "make all", "make test", and if everything goes OK "make install".
