Hi, I’ve got Ruby 1.8.4 compiled and installed on a Ubuntu box. I installed rubygems 0.8.11. I then installed the postgres gem. Everything went ok. Doing a “gem list postgres” shows the postgres gem. So, when I fire up irb and do irb(main):001:0\> require ‘rubygems’ =\> true irb(main):002:0\> require ‘postgres’ LoadError: no such file to load – postgres from /usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:21:in `require__' from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:21:in`require’ from (irb):2 That’s not good. Why???! Thanks, Joe ---

I thought I had removed all traces of it. Maybe not. /usr/bin/ruby, /usr/bin/gem, and /usr/lib/ruby don’t exist. ---

Now, I’ve got to figure out why I’m getting: /usr/local/lib/ruby/site\_ruby/1.8/rubygems/custom\_require.rb:27:in `gem_original_require': no such file to load -- test/rails (MissingSourceFile) from /usr/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:27:in `require’ from /home/joe/projects/tanga/config/…/vendor/rails/activerecord/lib/…/…/activesupport/lib/active\_support/dependencies.rb:147:in `require’ from ./test/integration/…/test\_helper.rb:4 from ./test/integration/layout\_test.rb:1 from /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake/rake\_test\_loader.rb:5 from /usr/local/lib/ruby/gems/1.8/gems/rake-0.7.1/lib/rake/rake\_test\_loader.rb:5 rake aborted!

just a fyi, but i had the same issue hours ago on a fedora box and got it working using gem install postgres – --with-pgsql-dir=/usr/local/pgsql (extra – is correct),then manually making it… cd /usr/local/lib/ruby/gems/1.8/gems/postgres-0.7.1/ ruby extconf.rb –with-pgsql-include-dir=/usr/local/pgsql/include –with-pgsql-lib-dir=/usr/local/pgsql/lib obvious path changes as req., sorry 'bout the breaks (info found @ [http://www.nostalgix.org/blog/2005/06/hack-lot-ruby-on-rails-tiger-and.html](http://www.nostalgix.org/blog/2005/06/hack-lot-ruby-on-rails-tiger-and.html)) might have been easier using the tarball… 😛 ---
