after a few more changes, the build goes through, and i can load
my simple curry program into pakcs. there are still some bugs in
the process, and some things don't work (that is one reason for
some of the debug output still being enabled). but it is a start.

btw, i'd still be curious to know whether pakcs' behaviour in the
last examples below is expected (see comments), and why?

hth,
