gnuplot @5.0.1: problem with libgobject version (glib2 @2.44.1)

[stefan.becuwe@…]

Hello,

Just updated the installed ports without any problem. However, running the latest gnuplot results in

dyld: Library not loaded: /opt/local/lib/libgobject-2.0.0.dylib
  Referenced from: /opt/local/bin/gnuplot
  Reason: Incompatible library version: gnuplot requires version 4401.0.0 or later, but libgobject-2.0.0.dylib provides version 2401.0.0
Trace/BPT trap: 5

Is there a newer version of glib2 coming?

Thanks!

In the future, be sure and CC the maintainer of the port to ensure that she is notified.

$ port info --maintainer gnuplot
maintainer: mojca@macports.org, openmaintainer@macports.org

libgobject-2.0.0.dylib version 4401.0.0 is provided by glib2 @2.44.1 which is the current version. This message is saying that gnuplot was built with glib2 @2.44.1 but the current active version of glib2 (an older version not 2.44.1) only provides 2401.0.0.

This implies that you have an old version of glib2 active.

You should check which versions of glib2 are installed on your system and make sure that glib2 @2.44.1 is installed and active. The solution may be as simple as executing

sudo port selfupdate
sudo port install glib2
