Rails on Ubuntu
From OpenStreetMap
See http://wiki.rubyonrails.org/rails/pages/RailsOnUbuntu for details on getting Rails installed via gems.
May also need to install some of the packages and gems listed at Rails on Debian
Imagemagick 6.3.x on Ubuntu
Imagemagick 6.3 or higher is required for RMagick. It is not available in the repositories for Ubuntu so here is a workaround:
1. sudo apt-get remove imagemagick (only if Imagemagick is installed as an older version) 2. wget http://ftp.surfnet.nl/pub/ImageMagick/ImageMagick-6.4.0-0.tar.gz 3. tar xvvzf ImageMagick-6.4.0-0.tar.gz 4. cd ImageMagick-6.4.0-0 5. ./configure –prefix=/usr 6. make 7. sudo make install 8. sudo gem install rmagick
