Ok great.

It's painful to start all over again, so my hope is that -o and -k will help to recover a build failure.  Is there a better way of recovery from a build failure?

Yes -- simply try the same command again. The main reason I can think of why a subsequent attempt would work if the first attempt didn't would be software that doesn't specify build dependencies properly in the Makefile and thus has problems building in parallel; turning off the parallel build fixes this. I believe I to encountered trouble near the end of building InsightToolkit, with an error I didn't understand, and retrying allowed it to install. I don't remember if I was building in parallel or not.

"-o" means honor a statefile older than the portfile. This is only useful for port maintainers, who want to, say, test changes in the destroot phase of a port without having to go through the configure and build phases again. It's not a flag a user should use.

"-k" means don't clean the work area after the port is successfully installed. So this switch doesn't pertain to a user trying to install InsightToolkit either.

I can't see any reason to tell users to do that.

Yes, unless the portfile has changed.
