For the .deb packages, Debian-wise, I propose dropping wheezy support  
and making sure that X2Go Client builds against Qt5 in Debian jessie  
(afaik, that should be doable).

Ubuntu-wise, Qt5 was available in Ubuntu 14.04 already, as well, not  
sure how complete the packaging was at that time. Ubuntu trusty is the  
oldest .deb-based distro to support, I guess. So, if you can get X2Go  
CLient to build against Qt5 from Ubuntu 14.04, then the packaging  
should be trivial.

Alternatively, one could build-depend on Qt5 _or_ Qt4 in  
debian/control, let the build script setup the build env (if Qt5 is  
available, then pull-in Qt5, otherwise pull-in Qt4), then test what's  
available and build against what's availeble via X2Go Client's Makefile.

For RPM-based distros, the x2goclient.spec can be if-claused heavily  
to support both build paths (Qt4 and Qt5).

Needs some patient to get that fiddled together, but it's doable.
