From time to time I need to prepare presentations, and I use the beamer class plus the minted package.
I would like to know why sometimes I need to delete the aux file generated by pdflatex to successfully compile. Is there any additional step aside from invoking pdflatex?

latexmk -pdfwould help (you can even set up alatexmkrcfile with instructions about what kind of files should be cleaned up after the compilation) – henrique Mar 26 '12 at 2:08
