thanks for confirming that this is a known problem/limitation. I will try to remember this if I 
encounter that situation again. it sure is unfortunate, though, that an installed package can
get unwittingly uninstalled especially one that is part of the texlive "mess" ...

but anyway. I have used macports long enough to really appreciate how much smoother it works these
days. thanks a lot to everybody involved!.
