Since yesterday, I pressume due to an update (with gremlins on), I get this error trying to start virtualbox
% virtualbox
Qt FATAL: Cannot mix incompatible Qt library (version 0x50b01) with this library (version 0x50b00)
Trying to revert those three pkgs didn't make a difference, although I did not reboot because I thought libraries do not get loaded into ram they are just accessible on demand (??).

Since this didn't revert the problem cause I am clueless what the problem now is
21/6/2018: SOLVED: Qr5-base needed an update and this is where the discrepancy was coming from
