You can fool it into thinking it has self hosted tools.

Just bootstrap it normally without the '--compiler' option and let it detect
gcc.

You don't have write perms over the nfs mount.  Maybe you're running
as root and have root squashed?  If so you may need 'anonuid=0' in the
mount specifications in /etc/exports on the host.

through bmake but fails in libnbcompat.  I'm attaching the 2 config.log files.  Do you have any insight to the breakdown
 here? Perhaps I'm missing something to include in the PATH or a library include?  Thank you anything you can offer.
