Jessica,

My guess is that this has to do with a difference between readline-4.x
and realine-5.0.  Do you need to use readline-5.0?

In HsReadline.hsc, you'll see that it includes <readline/readline.h>.

On FreeBSD, in /usr/include/readline/readline.h, I find this:

enum undo_code { UNDO_DELETE, UNDO_INSERT, UNDO_BEGIN, UNDO_END };
...
#define NO_MATCH        0
#define SINGLE_MATCH    1
#define MULT_MATCH      2


Do you have those in your system's readline.h?

You could probably port the readline library to use readline-5.0, but it
might be more work than you're willing to do.

Hope this helps,

Tim
