I guess you could do 'tar --version' to see if tar is gnu tar.  I'd rather
not make the pkgsrc builder define a variable to make things work.

On non-netbsd systems we install pax as part of the bootstrap don't we?
So we should have this issue everywhere.  I guess I don't feel too bad
about causing gnu tar to be installed.  It's pretty lightweight.
