Hi Christos,

Thanks for your bug report! I just had a brief look at this.
The member "errorString" is new to QT4.2, hence, are
you still running QT4.1.x by any chance? If so, you will
have to upgrade to at least Qt-4.2.* and we will have
to also change the dependencies in the ebuild
accordingly.

Best,
Markus

Hello Markus,

You are right, I am using qt-4.1.4-r2. I will upgrade it now but this will take
some time. I guess that will fix the problem.

made it use the qt4 eclass and moved the dep up to 4.2.

Thanks for the bug report.
