To make a patch I don't think you would need to have R and
knitr/Sweave installed. The patch would have to do with warning that a
module is enabled, not with what that module actually does.
But if you want to confirm that there is a problem (that you can run
shell commands from within a knitr/Sweave chunk), then you need to
have R installed. Sweave comes with R and knitr can be installed with
a simple install.packages('knitr') within R. Let me know if you want
instructions on this.
