Qt GPL replaces your PATH. Qt Commercial updates your path. I assume that 
there is a good reason for the difference.

The target audience of the installer is people who don't need additional 
packages and want to get started quickly and easily, ie. 95%+ of users. At 
the moment, you may be the only person who needs that extra stuff.

To make things even easier in the future I was thinking of including the 
necessary bits of Qt so that you don't have to download that in the first 
place. Also I would like to include eric4 and maybe other 3rd party packages 
(of which PyQwt would be a prime candidate). I would also consider making 
this a statically linked build - but that has issues that need to be thought 
through.
