gnuplot on ElCapitan fails due to Symbol not found

[chlangley]

Hello:

gnuplot port installs but then fails to run complaining of missing links.

Here is the story:

on OSX 10.11.3 MBP

For future reference: please CC the port maintainer (port info gnuplot). You can also add three braces to start and stop the code.

But this particular problem looks like something is fundamentally broken on your system. In particular something seems to be broken in /System/Library/Frameworks. I have no clue how this could have happened or what you can do about that (you can either copy the frameworks from another machine with a working OS or try to reinstall your OS). Please ask others for advice.
