make index failing again

So I've discussed this issue before but now something different
is annoyingly stopping me from completing a 'make index' in my
ports tree...

Why me?  Why is nobody else seeing this?  What have I done to bring
the wrath of the all-powerful mighty Red Daemon of the Internet down
upon my weary soul?
