As of October 20, Strawberry Perl is out!
It comes in two varieties: 220.127.116.11 and 18.104.22.168.
One caveat - you can only install it to the C or D drive, and there is
a separate download for each option. (But you could build it yourself
and put it anywhere you want if that limitation really bothers you.)
Win32::GUI builds cleanly out of the box with 22.214.171.124, thanks to work
done earlier by Laurent Rocher. (At least, I think that's who did the
work to make Win32::GUI build with dmake instead of Visual Studio.)
I even ran a few of the test scripts in the demo folder, and they run
fine. (By the way, I got the error 'Can't call method "STORE" on an
undefined value during global destruction' when exiting Notepad.pl.)
To install Win32::GUI on Strawberry Perl:
Run the CPAN client. (It can be found in c:\strawberry\perl\bin\, but
there's also a Strawberry Perl item in the start menu from which you can
run the CPAN client.)
In the client, type 'install ExtUtils::FakeConfig' and hit enter.
When that's done, type 'install Win32::GUI' and hit enter.
That's all there is to it.
