I'm trying to install your Rsubread pkg for a user here on our cluster. The problem seems to be that I'm getting basic C errors which is odd for such a long-lived package. Is there a missing header file in this package?

The errors below are from R 3.4.1, but I get essentially identical ones from other R versions using gcc/4.8.2.

The install was initiated, after loading the R/3.4.2 module, with:

> source("http://bioconductor.org/biocLite.R")
> biocLite("Rsubread")

The ifreq struct should be defined in <net/if.h>, which for me is found in /usr/include/.  Is it present on your system, and included during compilation?
