Ruby 1.9.2 RVM w/iconv FreeBSD installation HOWTO

The Problem

Recently, trying to run some of my crutches (the Ruby thingies I use to help me sysadmining) under RVM, I've found that require 'iconv' doesn't work. Since I knew it's working in standard lang/ruby18 and lang/ruby19 ports I started to search where is the trap and have found that. Here's how.

Prerequisites

rvm installed
system ruby installed

How to Avoid an Hour of Trouble Installing Thin on Win

Install RubyInstaller's 1.9.2
Install devkit (https://github.com/oneclick/rubyinstaller/wiki/Development-Kit)
gem install win32-events --platform=ruby (not actually necessary but this pulls up some useful libs for further dev process)
gem install eventmachine --pre --platform=ruby
gem install thin --platform=ruby

We couldn’t find that file to show.

Often in the last year I (and other experienced FreeBSD users) face the same problem: "Error loading external entity" messages and thus, the compilation failure.

I've found several ways to fix it and the likes:

You should open /usr/local/bin/xmlto script and comment out the following line:
```
XSLTOPTS="$XSLTOPTS --nonet"
```

The fix works only if you've got a live Internet connection. The best way probably is to fix local dtd catalogue layout for docbook* things but I still don't know how; advise needed!

Yesterday I've encountered a sudden bug: my four years old script rafused to work. After a slight rewrite I got some kind of descriptive symptom in the syslog:
