The output of the source command should show something like this:
> source("https://bioconductor.org/biocLite.R")
Bioconductor version 3.2 (BiocInstaller 1.20.0), ?biocLite for help
If you're not seeing that, then you're not using the latest version of Bioconductor. You should make sure you're running the latest version of R (3.2.2), before running the source command again. If that still doesn't work, try running remove.packages("BiocInstaller") and then re-running the source command.
