On August 24th (yesterday, at time of this post) Perl 5.8.0 became available for the Sharp Zaurus SL-5500 / SL-5600 series PDA's. I am working on downloading and installing it. Once I've got the installation to my liking, I'll edit my original post in this thread.
Anyone interested in trying the latest version for the Sharp Zaurus, you can download it here: Perl_5.8.0_arm.ipk.
There is a good discussion on the development and hosting of this latest port on the Zaurus Development Forum, here: Notes on Perl 5.8.0.
UPDATE: So far I've been unable to get the existing Perl_5.8.0_arm.ipk file to install. There seem to be several issues; a number of tar files with bad headers, and probably most importantly, the ~/tmp directory (in Internal Memory) fills up before the 34mb install is shifted off to SD. I'm working on getting in touch with the person who ported it to see if I can bring the issues to his attention. Hopefully it won't be long before we've got a *full* albiet *big* implementation of Perl on the Zaurus. Until then, use Perl 5.6.1 as described in my root node for this thread.
Good luck, and let me know any comments you have so that I can get them into a subsequent edit of this thread's root document.
