It seems that in Darwin there is a BSD libedit, which is symlinked
as libreadline and has a corresponding readline.h. This breaks
Octave and probably other builds.

In addition, there is no BSD version of libreadline. BSD libedit
has been in Mac OS X since at least 10.2. The new things are the
compatibility wrappers in readline/readline.h and, and this seems
to me to be Apple's invention, the symlinks readline/history.h-
>readline.h and libreadline.dylib->libedit.2.dylib. The overall
effect is the same (licensing issues aside) as having included a
very old incompatible version of GNU readline.
I maintain that this is broken.
I used the Gentoo package manager to install readline on my Tiger
system; this replaced /usr/include/readline/* with GNU's version, and
replaced the symlink to libedit.dylib with a "real" version of
libreadline.
I did not notice any breakage of other things, but have not compiled
any Cocoa apps. The only things that I have built with xCode, since
making this change, have been device drivers - nothing that relied
upon readline.
Are there problems with installing GNU readline?
