Patch attached.  It adds these symbols to libsrc/interface/nglib.cpp and
libsrc/visualization/vssolution.cpp .  Just put this in debian/patches,
and add its filename to debian/patches/series.

Tests completed:
      * The package builds and installs
      * ng runs when installed
      * Salomé's netgen plugin configures and builds

Thanks,
-Adam
