Subject: Ruby 1.9 build requirements

I have just installed Ubuntu 9.04 Server Edition. I followed the
instructions on the Ubuntu site to build Ruby 1.9
(p243) from scratch. The build appeared to work, but gem installs
complain about missing zlib.

I have found a number of sites that list the prerequisite packages,
but there is some amount of disagreement about what needs to be
installed prior to making Ruby 1.9. Does anyone have a definitive list
of prerequisite packages?

Thanks for your help.
