[AUCTeX] Ubuntu Jaunty and pdflatex

[Alan E. Davis]

How can I enable pdflatex for auctex on Ubuntu Jaunty?  I am using texlive 2007, stock for Ubuntu Jaunty.  

I am able to compile latex code in the bash shell with pdflatex.  But AucTeX is not aware of it.  I type C-c C-c, and even if I enable TeX-PDF through customization, and also with C-c C-t C-p, neither pdflatex nore TeX-PDF are known by Auctex.

I have seen many questions similar to this on various mailing lists, and always answered incompletely.  

Is there a config file where I can specify this?

Thank you,

Alan Davis
