On Ubuntu 13.04 I installed Tex Live 2013 and then compiled Kile from source (in order to avoid the large amount of dependencies that come with Ubuntu's version of Kile). Kile runs, but when I tried to compile a .tex file using PDFLaTeX I got the following error message:
[PDFLaTeX] failed to start
How do I make Kile find PDFLaTeX?
