Yes, it is mostly a packaging problem. The ubuntugis unstable repository 
contains an ecw package that works with GDAL 1.10 up to Ubuntu 13.04. 
Until now, nobody managed to build it for GDAL 1.11 and newer ubuntugis 
releases.

It was already asked on the gdal-dev and ubuntugis mailing lists:

<http://osgeo-org.1560.x6.nabble.com/gdal-dev-Issues-building-ECW-JP2ECW-driver-as-a-plugin-on-Ubuntu-td5156322.html>

<http://lists.osgeo.org/pipermail/ubuntu/2014-August/001154.html>

but unfortuantely noone could give a better workflow than my workaround 
(which works for 14.04, but does not add python support).
