Building gnuradio 3.7.5 from git repo on Ubuntu 13.10 is fine except  
qa-qtgui test fails, with unfound libQt5Svg.so.5. Making links  
from /usr/lib to either libQt5Svg.so.5.3.2 or libQt5Svg.so.5.3.1 finds  
the lib but both fail with unrecognised symbols.  
What version of Qt does work with 3.7.5 ? Or am i heading down a dark  
tunnel?

GNU Radio does not yet support QT5, so you’ll have to install the QT4  
library packages.
