That configures and starts to build.  One noticable difference is that
the './configure' step outside pkgsrc consistently names the platform
"powerpc-unknown-netbsd9.99" while under pkgsrc it calls it "powerpc--netbsd"
then during the build step gets "powerpc-unknown-netbsd9.99" and fails.

The build ultimately fails with:
