[BioC] Building GenomicRanges1.14.3 on Centos6

[Horne, Nigel (NIH/NLM/NCBI) [C]]

I am a system admin who has been asked by a user to install GenomicRanges, however it is failing.  I know absolutely nothing about R, so I'd like some (gentle!) help on how to install it.

This is on CentOS6, with gcc 4.4.7, R2.15.1.  The error I get is:

bash-4.1$ /usr/local/R/2.15.1/lib64/R/bin/Rcmd INSTALL GenomicRanges_1.14.3.tar.gz

Stddef.h does exist and is installed, this simple C program compiles correctly.

[hornenj at c6build64 tmp]$ cat std.c
#include <stddef.h>

main()
{
}

Thanks,
