ppm can't unpack the modules from the repository

The trouchelle repository bundles the modules into zip archives (instead of the more usual tar.gz format), and older versions of ppm can handle only the tar.gz format.

However, since you're using perl 5.8.8, I would expect that you have a version of ppm that does handle the zip format. What do you get when you run ppm version ?

Also, which build of ActivePerl are you running ? I get:

C:\>perl -e "print $ActivePerl::VERSION"
822
C:\>
