Beating a nuisance
I was having a problem with trying to get rails to play nicely with my development machine. I was really frustrated with trying all kinds of various solutions, but none of them would actually work. My problem was consistent:
/usr/lib/ruby/gems/1.9.1/gems/activerecord-2.3.8/lib/active_record/connection_adapters/abstract/connection_specification.rb:76:in `rescue in rescue in establish_connection': Please install the postgresql adapter: `gem install activerecord-postgresql-adapter` (no such file to load -- pg) (RuntimeError)
