Re: Building on MacOS 10.5

I have gnuplot working on OSX 10.4 (Tiger), and a patch queued to
gnuplot CVS to automate this.  However, that is not sufficient for
OSX 10.5 (Leopard).

In a nutshell, the problem is that Leopard ships with a gnu readline
emulation library built on top of the BSD editline library.  But it is
not a complete emulation, and the initialization commands are different.

The most complete description I've found of the problem, and fixes for a
different package (iPython) are here:

Another report (in Japanese, but the key parts you can cut-and-paste)

  http://www.python.jp/pipermail/python-ml-jp/2007-October/004150.html

We should aim to get gnuplot's autoconfigure script to recognize this
state of affairs and adapt accordingly.  I'll happy accept volunteer
fixers or guinea pigs testers.
