New description:

 I've installed Lion a couple of days ago, then port-uninstalled
 everything, port-cleaned everything (with --all option), then port-
 selfupdated and reinstalled the stuff I need. Now every time I try to use
 "scale" filter, mencoder gives me "Segmentation fault". Mplayer, by the
 way, works fine. Mencodering without scaling works fine. I've tried
 different sources, got the same result.

 Here is what happens when I run mencoder (with debug variant enabled) in
 GDB:
