I'll start with a hi!
I'm actually a puppyLinux person and have just completed (with problems) sorted out adding RazorQt as a package to that. I'm actually building a Qt Application Puppy, replacing non-qt apps with where possible qt apps.
And yes we do have a magela based puppy.
I actually came across to your system to find out if you had a package I could use for a simple small business, similar in format to the three column systems book, but with simple order, invoicing and sales receipts added, I doesn't seem to exist though, those out there are just too complicated for what's wanted in a mom-and-pop store with their first computer!
However, when looking through the specs and wants for magela2 I saw that razorqt was listed, but nothing further on what's happening, so I thought I could offer my services and build one for you while i'm still fresh with my own build experience.
The only problem I have is your alpha is of a size I cannot work with, as being a satellite connection 4gig would be two-thirds of my 6gig monthly allowance. If someone has a cut-down url, say for a gig or so size, I'm quite willing to create and debug, but not at any cost! Also I only work 32bit, I don't have anything larger and quite frankly don't need a 64bit box so I never bought one.
The other thing you need to check with using qt is that your binutils is at least version 2.20.51.0.11 or later, or has it's patches (including the patchfile 1.0) as this version fixes a lot (most) of problems with the 'ld' Dynamic Linker Loader and Qt4 from 4.7.4 and the later 4.8.x plus the proposed qt5 standard all make serious use of that toolset.
