Got one bad bit of information from my previous post.  The problem DOES 
exist when just performing a pkg_deinstall.  Apparently the one test I 
based my earlier post on wasn't repeatable.  The problem is not with the 
portupgrade script itself.

Dug in quite a bit further with this today.  When pkg_deinstall calls to 
pkg_delete a .nfs file is created which is showing as being actively 
accessed by the ruby process.  This file vanishes once pkg_deinstall 
quits.  Due to that file, even attempting a "rm -rf" on that directory 
will fail within pkg_deinstall.

For testing this out, we added a cheap hack to the portupgrade script 
immediately after the call to pkg_deinstall that just removes the 
directory once pkg_deinstall has ended.  This works, but has no logic or 
error checking at this point.

The pkg_deinstall script does not report that it didn't complete, so the 
main portupgrade script just keeps on going as though there were no errors.

With that being said, what I believe needs to happen in the short term 
is to have a check within the portupgrade script where if the 
pkg_deinstall returns successful and the /var/db/pkg directory still 
exists, delete it.  This would be right around line 1721.

Obviously the more correct thing to do here would be to correct 
pkg_deinstall's behavior.  That looks like it may be quite a bit more 
clever to do, thus my recommendation for fixing portupgrade now, and 
revisit pkg_deinstall later.  I'm just concerned that the real problem 
may have more to do with the ruby engine and NFS than this script, which 
may take many months to correct.
