No matter how you phrase it, loading both Qt4 and Qt5 into /usr/bin is a
kludge. There are programs with identical names but different
functionality in both versions. The better way, IMO, is to install both
in separate directories and just manipulate PATH to select the one you want.
Note that this does not apply to running applications as there is no
naming collision with the library names.
