pdf, dvi, preview mac os x

[peko]

i read the discussion about the problems in previewing with lyx and mac osx.
Although I think I really followed the instructions (first installing a
teTex base, which I did with the wonderful i-installer, then get the other
packages ghostscript 8, cm super, freetype 2, libwmv and iconv conversion
support, ImageMagick and then finally the lyx installation), I'm not able to
manage to get the preview work.
Any ideas out there of what to do?
Thanks
