I figured it out.  I was not copying my plustek.conf file to the proper place (in my case
/usr/local/etc/sane.d/plustek.conf).  However, since I was working in the same directory I had
written the correct plustek.conf file in, scanimage was working there.  When I would go to another
directory, it would stop working.

That's because the plustek backend looks in the current directory and if it finds a plustek.conf
file there, uses it instead of the one in /etc or /usr/local/etc.  That really threw me for a
loop.

The man page for sane-plustek doesn't mention that it looks in the current directory for
plustek.conf.
