[Eric] Install eric6 on Mint 17.1

[Tony Arnold]

When installing eric6 on my Linux Mint 17.1 systems, it complains it
needs Qt 4.8.0 or better, or Qt 5.3.0 or better. I have Qt 4.8.5 and Qt
5.2.1.

Qt 5.3 is not in the Mint repositories yet and is unlikely to be for
some time as it is based on Ubuntu 14.04 and will be for the next year
or so.

I've tried Qt 5.4 using the on-line installer from the Qt web site
(www.qt.io), but this installs into $HOME/qt if installed without sudo
and into /opt/qt if installed as root. Not sure either of these
locations will be discovered by the eric6 install script.

So, how best to install Qt 5.3.0 (or better) in a way that ensures the
eric6 install script will find it? Or is there a debian style repository
somewhere with qt5 available?

Regards,
Tony.
