>How-To-Repeat:
See above.
>Fix:
A tell-tale seems to be:

  src/3rdparty/opennurbs/CMakeFiles/OpenNURBS.dir/cmake_pch.hxx.gch

Unless it has come to mean something else, the "pch" in the above
file may mean "pre-compiled header" and these have frequently been
a problem on NetBSD/i386.

In the past, such situations were worked around by disabling pre-
compiled headers, but I'm not sure how that's done with 'cmake' in
the mix.
