Darwin frotz.local 7.4.0 Darwin Kernel Version 7.4.0: Wed May 12 16:58:24 PDT 
2004; root:xnu/xnu-517.7.7.obj~7/RELEASE_PPC  Power Macintosh powerpc

>Description:
Darwin has a libedit which does not include readline support.
devel/readline/builtin.mk correctly sets IS_BUILTIN.readline to "no", because
there's no readline.h, but then it sets USE_BUILTIN.readline to "yes" anyway
(at line 91). This causes readline to not be built, and so the package depending
on it will fail (or at least, fail to use readline)

>How-To-Repeat:
Try to build, eg, lang/hugs on OS X. Note the warning about "readline not found,
ignoring --with-readline"

>Fix:
I think the whole INCOMPAT_READLINE thing is confused. It should just be
looking at IS_BUILTIN.readline. But I don't have a SunOS box to test against
