/etc/alternatives is not the proper solution either. It has mostly the same 
design flaws as qtchooser, with the additional issue that the choice is a 
global systemwide choice rather than a runtime one, which breaks multi-user 
setups and concurrency (can't build apps against different Qt versions 
concurrently).

The correct solution is to use unique (i.e., in practice, suffixed) binary 
names.
