Installing Merb, DataMapper and Postgres on Ubuntu
This isn't particularly difficult, but if you're not familiar with Postgres on Ubuntu it could take you ten minutes to work it out:
$ sudo apt-get install postgresql-8.2 postgresql-server-dev-8.2 -y $ sudo apt-get install libsqlite3-dev -y $ sudo gem install merb do_postgres
merb gem depends on the
do_sqlite3 DataMapper database driver, so we need the
libsqlite3-dev package in order to compile it. You can remove it afterwards if you like.
