I just compiled ruby 1.9.2 from source and tried to install rubygem
1.3.7 (I did check if it was already installed on not) but it errors
out. Does anyone know what is the problem and how to fix it?

I am having the same problem. I am on an ubuntu system: Ubuntu 10.04 LTS
- the Lucid Lynx . I downloaded and installed ruby 1.9.2, and ruby -v:
ruby 1.9.2p0 (2010-08-18 revision 29036) [i686-linux]
gem -v is 1.3.7.
But when I try to run gem install ...
gem install rails -v 3.0.2
ERROR: Loading command: install (LoadError)
no such file to load -- zlib
ERROR: While executing gem ... (NameError)
uninitialized constant Gem::Commands::InstallCommand
So I downloaded gem1.3.7 and when I run
ruby setup.rb
I get:
ruby setup.rb --help

Julian, it appears you already have gem installed, so you don't need to
compile it from source. What you are missing though is a zlib library.
What you need to do is cd into your ruby 1.9.2 source code dir then into
ext/zlib (so for me it'd look like
/home/username/Desktop/ruby-1.9.2-p0/ext/zlib/).
Then run:
ruby extconf.rb
make
make install
Then you should be able to run
gem install rails
