Subject: Problems trying to use readline or editline ...

I'm having some trouble with either of the line editing libraries available
to me. If I build Python with libreadline, I get "staircases" in my
interpreter output:
>>> s = 1
>>> a = 3
>>> etc.
So I figured I'd give Rich Salz's editline a try. It seems to be missing a
couple readline functions. When I link I get:
myreadline.o: Undefined symbol _rl_insert referenced from text segment
myreadline.o: Undefined symbol _rl_bind_key referenced from text segment
I'm running on BSD/OS 2.0 with GCC 2.6.3 as the compiler. My configure line
was
./configure --with-readline=/home/dolphin/skip/src/editline \
--with-dl-dld=/home/dolphin/skip/src/dl-dld,/home/dolphin/skip/src/dld
For editline I tried several things before arriving at something that does
work ... sort of. First I commented out the tab key binding in Python's
Parser/myreadline.c then had to fiddle with editline.c to get tabs to
insert. The diffs below seem to work, but have no notion of tab stops (I
like 4-char tab stops).
I'd be grateful if anybody had a solution to the readline staircases or a
better solution for making editline work.
