My experience: My current OS install dates back to Leopard, which was installed on my MacBook Pro back when I purchased it in 2009. I've upgraded to each subsequent OS X release since then, and maintained a development environment utilizing X11 (for gnuplot) the entire time.
It is my understanding that the X11 included with OS X was actually a snapshot of XQuartz at the time of OS release, so the config data is in line with what XQuartz expects. In the Unixy bits, OS X upgrades are a lot like other Unix-like operating systems in that package operations remove the application, but not the configuration.
After installing XQuartz, gnuplot continues to run just like it did under previous versions of OS X. I simply ran the XQuartz installer and got back to work.
Yup, just like Ubuntu. Gnuplot does not depend heavily on whatever window manager you are using's config anyway, it just needs the X server (similar to R stats)
