Greetings,
HTTPD::Bench::ApacheBench (0.73)
I'm fairly certain that is optional and only really needed for testing. Don't worry about it.
Test::DBIx::Class (0.42)
This is only needed for testing, and is a pain to install. Unless you are trying to do development, don't worry about it.
Readonly::XS (0.01)
Ignore the message. If you check with a dpkg -l you'll probably find the xs version is installed. The $VERSION isn't detected or told properly. If it is installed, it is very likely the right version, even if not detected properly.
WebService::ILS (0.07)
On newer versions this is the only one that you will probably care about. I usually cpan2deb it, and then sudo dpkg -i it into place, but that may not be the best solution, if it isn't already available packaged in the default or koha repositories. BTW, I do believe this a problem with the kohadevbox too, but I didn't report it when I encountered it. GPML, Mark Tompsett
