Latex question : about Asian characters..


I’m using kile to make pdf. Since I need to enter Japanese characters from time to time, I installed the necessary files following this guide:
How to install CJK packages with UTF8 encoding on Fedora 8 at DU Run Senses

It turned out that “pdflatex ***.tex” would complain like this:
pdfTeX warning: pdflatex (file cyberb81): Font cyberb81 at 720 not found
kpathsea: Running mktexpk --mfmode / --bdpi 600 --mag 0+360/600 --dpi 360 cyberb30
mktexpk: don’t know how to create bitmap font for cyberb30.

However the pdf could be made correctly by using “latex 1.tex” then “dvipdf 1”. In this way, a 1.pdf would be generated correctly.
But why pdflatex fails to know the font?
thanks a lot.
