I have installed a copy of Scribus on my MBP, as I can't afford to upgrade InDesign from CS1, my computers run 10.6.7, so ID won't really run and Lion will kill it, and although I have an external drive that will boot the MBP into 10.4, I've found that's more hassle than its worth as I don't need it that often.
Scribus looks as if it'll do what I want, though in a much more clunky interface, and of course it seems not to import RTF, only plain text ... I can live with that.
My problem is that it comes up with an alert that my computer doesn't have GhostScript installed, which it might need. I therefore downloaded the newest functional — i.e. non-source-version — of GhostScript, unzipped/tarred whatever it ... and I found a unix executable and a couple of text files, neither of which told me what I should do with the unix executable, where I should put it.
I am minded of the person on the Windows forum who said they would never want to have a computer that they didn't have to beat into submission (i.e. a Mac)

Advice gratefully received.
