gnudatalanguage: Library not loaded: /opt/local/lib/libform.5.dylib

Hi, I've updated Xcode, recently updated to El Capitan, downloaded the newest version of macports, installed, etc. The purpose was to run GLD (IDL free version). I get the following:

~: gdl
dyld: Library not loaded: /opt/local/lib/libform.5.dylib
  Referenced from: /opt/local/bin/gdl
  Reason: image not found
Trace/BPT trap: 5

Then I tried downloading GDL sourcr code, and when i do the cmake .. it says I don't have a wxWidgets library. So I downloaded wxWidgets, and that's proving to be cumbersome too, as the make is failing to produce certain files, because when I do "sudo make install" it can't find some stuff it should have created with the make.

What a maze. I had everything running before these new updates. I didn't remember it being this complicated. Help!

My next idea is that I need the older version of that dylib, or ncurses5. Again, no idea if I can install this on itself, I would have expected the OSX to have installed this stuff already. And if it is a path anything like the wxWidgets path I was trying, I won't be able to carry on, it will fail.

Thank you.

You're correct that libform is part of ncurses. The problem is simply that ncurses was recently updated to version 6. So /opt/local/bin/gdl needs to be rebuilt with the new ncurses.

You should merely need to run:

sudo port selfupdate
sudo port upgrade outdated

The curious thing, though, is that this change was made in r139469 which predates the release of OS X 10.11 El Capitan so I'm confused as to how you are running into this problem. If selfupdating and upgrading outdated ports doesn't fix it, then certainly running rev-upgrade will:

sudo port rev-upgrade
