Subject: [yocto] Discovering available Perl modules OR writing recipes for your own

Hi all,

I'm working on a recipe for pullledpork, which is a Perl app which grabs and combines Snort rules from various sites.

My questions all revolve around pulledpork's various module dependencies.

pulledpork tries to use the module Crypt::SSLeay and in my current configuration it can't find it. It is very easy to write a little recipes that provides this module and forge ahead.

But I'm not sure that that is the correct thing to do...especially as it looks like I'll have to do the same thing for another ten or so tiny modules if I take that approach.

First, is there some way that I can find out whether that or any particular Perl module is provided by some recipe somewhere? My plan would be to RDEPEND on every available Perl module, forcing them all to be installed in the right place, run the pulledpork script, do the right think to provide any modules still missing until the script can actually complete, and then remove from RDEPENDS all previously included modules that don't show up a values in %INC. So far, so good, but I don't know how to even locate all the Perl modules that are already available.

Second, if the modules really are not available is there a better way to package them up than writing individual recipes for each and every missing module?

Third, are there naming conventions that should be followed? For example there is a recipe for liburi-perl that provides the very simply named Perl module URI.

Thanks!
