Well: installing MT wasn't too bad after all. The instructions were clear and mostly accurate, but they could have spelt out the need to remove the commenting '#' at the beginning of the StaticWebPath line in the mt.cfg file!
My installation is on a Mac OS X 10.1.5 system. Fortunately Perl and all the important modules were there and waiting and I didn't need to install any of these. I can't remember though whether this version of OS X originally shipped with Perl, or I had to install it. I have vague memories that some time ago that's what I did.
Following my earlier rant about Radio and Userland, I shall comment here on any notable differences, pros and cons, etc of the two systems.
