Hey all,

I'm trying to add to install the program Bangkok as a gem, but every
time I try I get this error.

sudo gem install bangkok
/usr/local/lib/ruby/site_ruby/1.9.1/rubygems/package.rb:10:in `require':

I've tried reinstalling the latest version of Gems, but it didn't seem
to help. Any ideas? Thanks!

nothing is wrong with your rubygems. you don't have zlib in your ruby install.

It depends on your OS/distribution. On Ubuntu/Debian install the
package zlib1g-dev, (which contains the header files ruby's zlib
extension needs to build properly) then re-configure, make and make
install your ruby-1.9 which it looks like you installed yourself from
source. Then reinstall rubygems. Other systems will name the package
with zlib header files differently, but otherwise instructions are the
same.
