I will see what I can do when I find the time.  I do recall
encountering one other package which had this identical problem but I
don't recall what that package was.  It seems likely that it is
somehow related to using GCC 4.0.1.

Ugh.  I do think that readline 5.0 itself has a minor bug in that ldd
on libreadline.so does not show a dependency on the curses library,
even though it is obviously required.  This means that the linkage of
libreadline.so is incomplete.

% ldd /usr/local/lib/libreadline.so.5
