installing cdo failed due to deprecated.cxx11 PortGroup

[boervu]

When installing cdo using Macports (OSX 10.14.6 Xcode 10.3) I get the following warning, resulting in a failure of installing cdo:

Warning: -----------------------------------------------------------------------
Warning: The port 'cdo' uses the cxx11 PortGroup which is deprecated.
Warning: Please instead specify the required c++ standard directly using
Warning:     compiler.cxx_standard  2011
Warning: replacing 2011 with newer standards (e.g. 2014, 2017) as required.
Warning: For more details see https://trac.macports.org/wiki/CompilerSelection
Warning: -----------------------------------------------------------------------

Tried to work around it by manually installing cdo, but get the same message, and basically the installation works the same as using macports.

The Milestone field is for use by Macports team members only, please do not set it.

In the future, please use WikiFormatting and add the port maintainer(s) to Cc (port info --maintainers cdo), if any.

That's simply a warning and not the actual error. Please attach the main.log file.

Error is:
