[xcrysden] XCrySDen now available in MacPorts

[David Strubbe]

Hello all,

I would like to announce that I have successfully included XCrySDen version
1.5.60 in the MacPorts package manager (www.macports.org) as of today:
https://www.macports.org/ports.php?by=name&substr=xcrysden. This link can
be added to the page at http://www.xcrysden.org/Download.html#__toc__1.
The code can be installed by "port install xcrysden +x11".

Previously XCrySDen could not be included properly in MacPorts because the
code only worked with a very old version of Mesa on MacOS; however now it
can work with Mesa 10.5.4 (as well as with system OpenGL libraries),
according to my tests on Yosemite (OSX 10.10.5). The key was the patch
described by Hideyuki Kamisaka on Nov. 5, 2014 in this email list, namely
setting "-accum          false" in the Togl options.

I have in the process also produced an updated version of the file
system/Make.macosx-x11 for Make.sys, which had been produced many years ago
and would not work on recent versions of MacOS. The new one is included
below for any users who wish to build from source on MacOS. Tone, I
recommend you replace the old file with this one in the next release.

Best,
David Strubbe

# Use of the MacPorts package manager (www.macports.org) and 'port install
xcrysden' is recommended
# as an easier approach than using this file to build from source.
# MacPorts can be used to obtain the dependencies: port install gcc5 tcl tk
+x11 fftw-3
# tk must have +x11 variant; a different version of gcc can be used instead
if desired.

# X11 and OpenGL from system are being used.
