Thanks, that does the trick!

There's a little weirdness though.  Nothing I can't work around, but I'm
curious...

I start erl with the equivalent of -pa ~/projects/*/ebin , to add all my
local packages to the search path.

So I made a subdirectory, erlguten-2.1/ebin , and moved all of its .beam
files into it.

This seems to work fine for almost everything, except one thing:
pdf:get_font_alias/2 hangs.  It just never returns.

pdf:get_font_alias/2 only works if I don't move the .beam files, and run
erl with -pa ~/projects/erlguten-2.1

Any idea why this might be?
