[xcrysden] XCrySDen windows fail to show up

[Martin Kroeker]

Also see thread "problem running on OS X 10.9" from November 2013 -
there this problem was traced to incompatible (or broken) versions
of the Mesa OpenGL library. The solution given there was to either
install the "fink" versions of both xcrysden and mesa, or to use a
specifically patched MacPorts version. You might want to see if the
download links given in the thread still work.
