[NTG-context] context on texlive

[zhaohs]

Dear everyone,
   My Operating System is Ubuntu 6.06,I now use the context combined with cjk 4.6.0 shipped with texlivetest2006-live-20060215.iso to support chinese charaters ,when I use the command:
texexex --pdf my_file.tex,I can obtain the ultimate pdf files , but when I
use the command:
texexec --output=dvipdfm my_file.tex, though I can obtain the ultimate pdf
file ,but when I hit the hyperlinks in the pdf files ,the error message
happen as follows:"Unknown destination type 'View'".So the pdf file is bad
for presentation,why dose this happen?
    Furthmore, When I use texexec --output=dvipdfmx my_file.tex,I can get
the ultimate pdf files and it is good,but I also see the WARNINGs:
