[Pkg-scicomp-devel] Bug#475323: Bug#475323: netgen: Undefined symbols in libraries

[Adam C Powell IV]

Really?  I don't see these symbols defined anywhere, even inlined,
except ngtcltk/ngpkg.cpp which is not included in the library...

In any case, with my patch sent a few minutes ago, it builds even with
the existing flags (-O2), so it should work on HPPA.

Thanks,
-Adam
