Trying to install DESeq2 in R version 3.2.3 in ubuntu linux 16.04. I follow the instructions of the DESeq2 website:

source("https://bioconductor.org/biocLite.R")
biocLite("DESeq2")

at this point if I try to load the library with command library("DESeq2") I get a message that the library can'y be found. I suppose this makes sense because the installation appeared to have the following problems; in particular,

configuration failed for package 'XML'

which caused annotate, genefilter, and geneplotter packages to fail;

so at this point I tried install XML with:

install.packages("XML",dependencies = TRUE)

which fails due to configuration of RCurl. XML doesn't appear to be listed as a dependency on the DESeq2 website. Perhaps as a relative R beginner I am having trouble tracking down all the dependencies and the order in which I should install them. And suggestions would be appreciated.

the installation output was quite long and unwieldy, here are the ERROR messages that caught my eye:

checking for library containing OPENSSL_init_ssl... no
checking for library containing libssh2_version... no

  ---------------------------------------------
   Unable to find the LibSSH2 library on this

   To build with SSH support, please install:

I think you may need to install the devel version of libxml2 for the XML R package to be installed:

libxml2-dev

This is an unfortunate dependency case, because we don't even need annotate or XML functionality for the function we import from geneplotter:
