DISCLAIMER Note: this is currently is a draft and is not meant to be used yet. Many things that I'm looking to clean up and simplify. There may be things that don't work so only do this on a development system that you aren't worried about it being fubar'd

Get Nginx Source and prerequisite binaries, run configure and make to compile.sh

#some things we may need:
wget http://www.oss4aix.org/download/RPMS/zlib/zlib-devel-1.2.8-1.aix5.1.ppc.rpm
rpm --ignoreos --ignorearch --nodeps --replacepkgs -hUv zlib-devel-1.2.8-1.aix5.1.ppc.rpm
#nginx: [emerg] using regex "\.php$" requires PCRE library in /usr/local/nginx/conf/nginx.conf:72
wget http://www.oss4aix.org/download/RPMS/pcre/pcre-8.35-1.aix5.1.ppc.rpm
