How to install tar.gz R package with non-zero exit

I want to install an old 2009 R tar.gz package in Windows 7, and have tried installing it using new and old versions of R (3.1.1 - output shown below, 2.7.0). This may not be pertinent to the solution, but I've set the path temporarily for R to recognize Rtools 31 using the code supplied in this solution.

I've seen this package used in recent journal articles so I know it's functional. If you would like to try installing this package it is available here.

Does anyone know how I can solve this cygwin warning, or Error: compilation failed problem/installation had non-zero exit status?

I really appreciate it, thank you very much!
