Error while compiling Enblend with MacPorts version 2.0.3

[Philippe Bernery]

Hi,

I'm trying to install Enblend (not directly but throw the installation of
hugin-app) but it fails with several errors and I can't figure out what
could be the origin of the problem.

Here is an extract of the compilation log:

The first and third errors appear several times.
Any idea?
