When attempting to install (through aptitude or apt-get) the dependancy to 
the virtual package qtbase-abi-5-3-2 somehow prevents this to complete.

This is a log of apt-get installation actions exposing the issue.

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 gammaray : Depends: qtbase-abi-5-3-2
            Recommends: gammaray-probe-qt4 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.

Package qtbase-abi-5-3-2 is a virtual package provided by:
  libqt5core5a 5.3.2+dfsg-4+deb8u1 [Not candidate version]

E: Package 'qtbase-abi-5-3-2' has no installation candidate

libqt5core5a is already the newest version (5.6.1+dfsg-3+b1).
libqt5core5a set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 707 not upgraded.
user at host:~$ 

It seems that libqt5core5a is already there, providing qtbase-abi-5-3-2, 
yet somehow this does not satisfy the gammaray package dependency.

Hope you can sort out why.
