The install seems to do the build all over, and stopping because of some error that it can not find something or other.  I can not remember what it was now, but it did start installing binaries into the prefix directory, but never finished.  Do I need to run install or is setting strip=yes enough?

Make sure you run the 'install' argument with all the same flags and FOO=X arguments.
That *should* make it not do any extra re-compile on the install phase.

I think the strip only happens during the install phase (too busy to look
right now)...

Thanks,
Ben
