The legal problem has never been with the Qt license, but with the GPL. It still depends on whether the law would consider Qt to fall under this clause: GPL> However, as a special exception, the source code distributed need GPL> not include anything that is normally distributed (in either GPL> source or binary form) with the major components (compiler, GPL> kernel, and so on) of the operating system on which the GPL> executable runs, unless that component itself accompanies the GPL> executable. An alternative to betting on what the law would say, is to get a "special exception" from the copyright holder.
