gnuplot Mac pkg

[Allin C. <cot...@wf...>]

Thanks to those who tested the package I mentioned in
https://sourceforge.net/p/gnuplot/mailman/message/34907517/

I've put up a revised version at the same place,
http://ricardo.ecn.wfu.edu/pub/gretl/gnuplot-quartz.pkg

In this version I have removed from the Distribution XML file the line

<options hostArchitectures="x86_64"/>

which is apparently more restrictive than I thought. This package just 
needs a 64-bit userspace, but including that line prevents 
installation on systems, such as OS X 10.6, that are not "fully 
64-bit" (10.6 has a 32-bit kernel). I think that should quell the 
"Cannot be installed" message.

I've also found and deleted a few more libraries that are required by 
gretl but not needed for gnuplot, so the package is a little slimmer.

A couple of comments on things I didn't include in the package:

* The libgd-based png terminal. I don't see much point in that one if 
you have pngcairo (unless perhaps, as Ethan has pointed out, you want 
to make animated GIFs). Also, including libgd will drag in a 
fontconfig dependency which is not otherwise needed. (Pango doesn't 
need fontconfig on OS X, it's better off using Apple's CoreText.)

* X11. Given the wxt terminal, IMO the X11 terminal doesn't add value. 
I guess I might have included it if Apple still included an X server 
with OS X by default, but making XQuartz a prerequisite for a gnuplot 
package seems unnecessary.
