Hi Kevin.

My system is 64bit, amd64 architecture with 64bit Erlang. It is Gentoo, btw.
By the means of my package manager I could get NSPR and Spidermonkey
installed (including headers), so we can resort to this if you think
this would make the process easier.

> The failing component in your build is a subsystem of Riak named erlang_js. Since we support Riak on multiple platforms, some of which do not have package management, we made the decision to automate the checkout and build Spidermonkey and nspr to simplify using Riak.

Most of the problems we're seeing relate to disagreement between Spidermonkey, nspr, and Erlang on the 32/64 bit nature of the build computer. Your build errors seem to indicate this is what's happening to you, too.
