Mac OS X 10.3 has <histedit.h> in /usr/include, and it seems to work.
However, the version distributed with 10.3 does not include the
readline emulation support distributed with more recent versions of
libedit (which, confusingly, put the readline emulation header in
<editline/readline.h>).

libedit comes from NetBSD, and is under the BSD licence rather than
the GPL. The simple use of readline in Lua could easily be achieved
with libedit's basic functionality; the emulation library attempts
to duplicate readline's hundreds of global variables, etc., and
may not be a perfect match :)
