Can't locate loadable object for module Win32::GUI in @INC (@INC contains: C:/strawberry/perl/lib C:/strawberry/perl/site/lib C:\strawberry\perl\vendor\lib .)

That just means it can't find the GUI.dll. It's looking for GUI.dll in the following locations (and in this order):
1) C:/strawberry/perl/lib/auto/Win32/GUI/GUI.dll;
2) C:/strawberry/perl/site/lib/auto/Win32/GUI/GUI.dll;
3) C:\strawberry\perl\vendor\lib/auto/Win32/GUI/GUI.dll;
4) ./auto/Win32/GUI/GUI.dll;

By my reckoning, the file specified in 2) should now exist ... and that would be fine.

I can see in the trouchelle zip, the following file:
blib/arch/auto/Win32/GUI/GUI.dll

So ... when you merge blib/arch/auto with C:/strawberry/perl/site/lib/auto, then C:/strawberry/perl/site/lib/auto/Win32/GUI/GUI.dll should definitely exist.

Either my instructions were faulty, or they weren't carried out correctly.

Cheers,
Rob

Update: If my instructions were faulty, I still can't spot the error :-)
