Yeah... I rebooted to enable iCloud on my iMac. :-)

No, other than rebooting the computer, I have not done anything at all.

Rats... that is the more difficult part. I have no end of problem running Dancer apps with Apache, so I keep on gravitating toward Starman. That said, when, for a while, I was running apps with apache and plain CGI, I would never have any issues other than an ever so slightly slow-poke performance.

Now I have close to 10 apps on this machine, so Apache is more problematic as either I run all the apps as plain CGI, or, any change in any one app would cause me to reboot apache, and thus restart all the apps.

Well, there is the log that does show all the regexp shenanigans that happen in selecting a route. Maybe I should enable that in a development version, and then keep watching the logs. And then when I get a wrong template, try to see what the messages were at that point. Hmmm... will try that.
