I'm trying to download the minfi and lumi packages, but get warnings with biocLite.

Your sessionInfo() tells us that you are on a Linux-based system. The biocLite() output starts by telling us that you are running a current version of R and an appropriate version of BiocInstaller.

Usually it is best to start with the first error that occurs. In this case it is from trying to install the dependency 'curl', and the attempt at installation, concluding with the error, is

The solution is to install the libcurl system dependency, using your operating system package manager. Once the dependency is installed, you should start a new R session and try again; note that you will (from your output above) run into a second system dependency requiring installation, so you can short circuit things a bit by installing openssl-devel. There may be additional errors from missing system dependencies, and the errors may be less helpful than these two.
