Actually, it's pure statistics.

Operating systems where Qt current is known to run:

	Windows
	Mac OS X
	Linux
	*BSD
	Solaris
	QNX

The majority of those have Perl.

And really, I installed ActivePerl on my IT-locked-down-and-virus-scanning 
laptop easily. I *really* do not understand what the big deal is -- was my 
experience atypical?

If you want to build a hugely complex framework like Qt, with a million lines 
of code, please understand you'll need to get a beefy machine and install some 
dependencies. If you don't want to build, try using one of the pre-built 
binaries.

Let me give you another important point:

we're trying to make the source releases to be as close as the repositories on 
which we (Qt developers) develop Qt. Why? Here are a few reasons:

 * we expect that most people who build Qt from sources are Qt developers 
    themselves (majority of users will download binaries and the stats prove 
    it);

 * we want to reduce the need of testing of the source releases by 
   "leveraging" the testing that is done daily by developers (that is, if the 
   source releases are substantially different from the repositories, the fact 
   that dozens of people compile Qt daily proves nothing);

 * we want the source packages to have cryptographic verifiability that they 
    weren't tampered with, by having the sources match *exactly* the 
    repository, which is already cryptographically verifiable.

I understand this makes some people's lives a bit (or a lot) harder. I 
understand Christian's concern of managing a farm of computers (by the way, 
don't you have a centralised software deployment solution?)

I'm just hoping that you guys understand that the changes are done for good 
reasons, they aren't done without forethought. And that Perl has been an 
industry standard for 3 decades.
