OK, I found libeditline for Linux, but not the readline wrapper.
Please try the patch below that should reject the readline wrapper.

Implementing support for libeditline itself would be fairly easy,
it only define the two functions
char     *readline();
void     add_history();
but is a different story from supporting the readline wrapper, and is left
as an exercise to the reader.

Cheers,
Bill.
