Interestingly, my own experience with Ruby, a few years ago, was almost 180 degrees opposite of the blogger's.
The two most frustrating aspects were documentation and deployment. The documents were sparse and useless and deployment was the hugest headache I've ever experienced, in great part due to Rubygems not working properly! They've probably improved it a lot since then, but it reinforced my long-standing belief that third party libraries are, more often than not, more trouble than they're worth anyway.
