Weird font error in FrameMaker 6 on Mac

[Steve Rickaby]

After installing the MacTex distribution (which might or might not be relevant), launching FrameMaker 6 in Classic produced the following weird, but non-fatal errors:

Dialog titled 'Font Installation Errors'...

Screen font conflict (NFNT 12888) Garamond Book 12 in suitcase ITC Garamond 2 and a font in suitcase OTF Cache 0

Screen font conflict (NFNT 14151) Garamond Book 14 in suitcase ITC Garamond 2 and a font in suitcase OTF Cache 0

Screen font conflict (NFNT 15445) Garamond Book 12 in suitcase ITC Garamond 2 and a font in suitcase OTF Cache 0

FrameMaker 7 in Classic did not give these errors. After a reboot, FrameMaker 6 didn't either.

I don't recall ever having seen anything like this before. Anyone have a clue as to what might be going on?
