Hi , I recently upgraded to Mandriva, and I've been having trouble with dvips/dvipdf. I keep getting these errors:

kpathsea: Running mktexpk --mfmode ljfour --bdpi 600 --mag 0+420/600 --dpi 420 ptmr8r
gsftopk: fatal: map file `psfonts_t1.map' not found.
mktexpk: don't know how to create bitmap font for ptmr8r.
kpathsea: Appending font creation commands to missfont.log.
dvips: Font ptmr8r not found, characters will be left blank.

any help would be great!
Thanks!!
