[gradsusr] How to install grads on Mac OS X 10.8.4 ?

[Jennifer Adams]

The de-support of X11 by Apple is unfortunate, and that is my best polite happy face way of saying it in a public forum. 

1. If X11 does not appear under the Applications->Utilities Menu, then you will definitely need to install XQuartz. 
2. If you do have libX11.6.dlylib under /usr/X11/lib/, then you should try setting the environment variable  LD_LIBRARY_PATH to /usr/X11/lib and see if that fixes things.
3. If setting the LD_LIBRARY_PATH environment variable doesn't solve your problem, then you will need to get to know the MacPorts Project (http://www.mactports.org).  MacPorts will effortlessly install all kinds of utilities, programs, and software libraries on your system. MacPorts puts everything under /opt/local/. 

Great news -- I have just discovered that MacPorts has a port for GrADS! A special shout-out of thanks to 'takeshi' and 'ryandesign' -- they are the ones who have set it up. As I am writing, it is installing the supplibs...

Anyway, when I built the GrADS executables for distribution, I linked dynamically with the X11 library installed by MacPorts under /opt/local/lib/, not the native X11 under /usr/X11/lib/. I really can't say whether I did that on purpose or not. I often switch back and forth between the two during testing to make sure that both are working properly. And since X11 support will not be a part of native OSX in the future, it's just as well to get started using MacPorts because that will probably be the way many third-party tools will be supported in the future.
