Ruby on Rails + Sybase + Ubuntu Linux - Error: Could not load SQLAnywhere DBCAPI library

Question

I'm actually brand new to Ruby and Sybase both, but here goes:

I'm trying to connect Ruby up to a remote Sybase server. (I've been successful with a local MySQL server.)

I've done:

gem install sqlanywhere
gem install activerecord-sqlanywhere-adapter

(and set up the stuff in the database.yml, of course)

Still, when I got to http://localhost/rails/info/properties, I get the following error:

LoadError in Rails/infoController#properties
Could not load SQLAnywhere DBCAPI library

Any help would be appreciated!
