Just grab the 5.10
trouchelle ppm zip file (or the ActiveState ppm tarball if you can locate it), unpack it to some location and:
1) Merge the blib/lib folder with the strawberry/perl/site/lib folder;
2) Merge the blib/arch/auto folder with the strawberry/perl/site/lib/auto folder.
I'll let you work out where the html documentation needs to go - though, of course, things should work ok without it.
If you want to utilise the 2 demo files in in blib/script copy them to strawberry/perl/site/bin (or to strawberry/perl/bin if strawberry/perl/site/bin doesn't exist).
I think that's about right ... probably safer to get ppm (which you have with StrawberryPerl) to do the job for you. Either:
ppm install Win32::GUI (for the ActivePerl build)
or
ppm install http://trouchelle.com/ppm10/Win32-GUI.ppd (for the trouchelle build).
Cheers,
Rob
