Hi Brian !

First, did you take a look at qt4.jam ?

A simple

import qt ;
using qt  : <where your qt is> ;

in user-config.jam (or Jamroot) should get you started using a pre-built 
qt. You can then use the targets like /qt//QtSvg as usual.
Please scan qt4.jam for more options, including target requirements and 
feel free to ask any remaining questions here or on IRC.

Second, I've tried to get Qt built by Boost.Build, but have given up due 
to lack of time and the missing 3rdparty library configure support. Qt's 
configure system allows a *lot* of different configs and emulating that 
(several image libs, X libraries, databases plugins (or not),you name 
it) is a huge task. If you're interested, I could see if I still can 
produce a tarball of it ;-)
It did build for my frozen Linux and Windows company setup at least. But 
using a precompiled Qt is much better as adding _thousands_ of files to 
a Boost.Build tree will slow things down noticeably...

Yours,

Jürgen
