build_all

#! /usr/bin/env bash
#
#  script to build gems for all relevant platforms:
#  - MRI et al (standard gem)
#  - windows (x86-mingw32 and x86-mswin32-60)
#  - jruby
#
#  here's what I recommend for building all the gems:
#
#   1. set up a vagrant VM guest running ubuntu lucid 32-bit.
#   2. install rvm, and install 1.9.3, 2.0.0 and jruby.
#   3. `sudo apt-get install mingw32`
#
#  as you build, you may run into these problems:
#
#  - if you're using Virtualbox shared directories, you'll get a mingw
#    "Protocol error" at linktime. Boo! Either use NFS or a
#    locally-checked-out repository.
#
#  - on ubuntus 11 and later, you may have issues with building
#    rake-compiler's rubies against openssl v2. Just comment the lines
#    out from ossl_ssl.c and you'll be fine.
#
#  - you may have issues with Pathname conversion to String in
#    bundler. Add this to the offending bundler file:
#
#      class Pathname
#        def to_str
#          to_s
#        end
#      end
#
#  - you may also have to hack rubygems.rb to eliminate a reference to
#    RUBY_ENGINE (just comment it out)
