install frescoba 2.18.2 in Ubuntu

[Bernard]

I installed Frescobaldi in Ubuntu using apt-get.  Which installed itself 
Lilypond. Very easy, unfortunately using version 2.16.2
apt-get did mention all dependencies, how it should be, but very outdated.

I would like to use Frecobaldi and Lilypond 2.18.2 Which causes a 
dependency hell for me.

Some links :
*http://frescobaldi.org/download
apt-get results on Ubuntu 14.04 results into installing version 2.16.2
so I tried install from source
* python 2.7.6 already installed, so that would do.
* install PyQt4. did not work. Q4.1 or higher should be installed. But I 
have allready QT5 installed

Outdated alternatives :
* http://frescobaldi.org/links  selected Ubuntu using ppa (which is 
often the latest version) date 2010, (some 300 day ago but I do not know 
the status)
* https://packages.debian.org/nl/squeeze/editors/frescobaldi Frescobaldi 
1.1.4-1

Is there a easy way to install Frescobaldi and Lilypond 2.18.2 on Ubuntu 
14.04? If so how?

Thanks.
