I've been trying to get GeoKit installed on my computer and for the life of me I couldn't understand why acts as mappable was showing up as an unknown variable. I followed the instructions (I'm using Windows):
ruby script/plugin install git://github.com/andre/geokit-rails.git
I added to the environment.rb
config.gem "geokit"
and I then ran:
rake gems:install
But when I went to my vendor/plugins directory, there was a "geokit-rails" directory but it was empty. I've also tried installing the gmap plugin the same way using ruby script/plugin install... it doesn't show me any error but there are no files in the directory at all.
I've now manually downloaded the plugin into the directory and ran install.rb from its own directory, but I still can't get acts as mappable to work inside a model... :(
