mac os x + netcdf + pykst

[Barth Netterfield]

Ahhh... a Mac OSX user!

We now have a nightly build for Mac OSX: 
https://github.com/Kst-plot/kst-build/tree/macos

Triggered by your query, I just updated the kst web site to reflect this.

Can you try that one and let me know

i) if it works at all? (and if you do get it to work, a web-site 
compatible mini-blurb on how to install it? I don't use macs, so I have 
no idea how to install this).

ii) if it had netcdf

iii) if the newest version of pyKst works with it (and if you had to 
make changes, what those changes were).

I will attempt to fix anything you find here.

Thanks!
