+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.
