Ruby Gems in Hoary

[Christoph Sturm]

looks like you dont have libzlib-ruby1.8 installed

try this:
sudo apt-get install irb1.8 libbigdecimal-ruby1.8 libdbm-ruby1.8
libdl-ruby1.8 libdrb-ruby1.8 liberb-ruby1.8 libgdbm-ruby1.8
libiconv-ruby1.8 libopenssl-ruby1.8 libpty-ruby1.8
libracc-runtime-ruby1.8 libreadline-ruby1.8 librexml-ruby1.8
libruby1.8 libruby1.8-dbg libsdbm-ruby1.8 libsoap-ruby1.8
libstrscan-ruby1.8 libsyslog-ruby1.8 libtest-unit-ruby1.8
libwebrick-ruby1.8 libxmlrpc-ruby1.8 libyaml-ruby1.8 libzlib-ruby1.8
rdoc1.8 ri1.8 ruby1.8 ruby1.8-dev ruby1.8-elisp ruby1.8-examples

the root cause for this is that debian (and ubuntu) have split ruby
into lots of small packages.
