I\'ve just moved over to Ubuntu 8.10 as my dev box; it\'s my first serious foray into Linux as a daily-use OS, and I\'m having a hard time getting Rails going. I have follo
On Debian (Squeeze):
libruby contains zlib for ruby amongst all the other stuff you'll need to make ruby work properly on Debian. So...
apt-get install libruby
Then...
cd /usr/local/src/ruby
make clean
make
make install
cd ../rubygems
ruby setup.rb
gem install rails
This made it work for me, but your mileage may vary. I did to a slight shotgun approach to zlib before finding that everything needed was covered by libruby.
