I have been using a MacBook Pro for several months, and I finally got around to upgrading Perl on it. I figured 5.10's release, and Christmas vacation, was a decent opportunity.
I ran into a lot of problems.
Bottom line is that now I have Slash running on my Intel Mac with native Apache 1.39, mod_perl 1.30 (with patch), and perl 5.10 (without threads), and the only brokenness -- that I know of -- that remains is missing functionality in Apache::Request that I don't use, and lack of thread-capable perl for mod_perl.
It was a long day making all that work, too. Dang it was long. Lots of futzing around. But I also now apparently have almost no more PPC apps running on a regular basis on my Mac: just Eudora. Which sucks. But not as much as every other mail app. I dunno, maybe I should give Thunderbird another go. I hate that it is not a native Mac UI, but it's not like Eudora has a great UI either. Maybe I'll try Mail.app again.
