The Java Portlet API is, like its name suggests, a Java API so Rails doesn't support that.
It is possible, however, to create something similar yourself. It's just that you'll have to do it all from scratch unless you can find an existing portal framework that's built on top of Rails. Also note that "a portal" doesn't imply that any specific "portal technology" is being used to implement it. In general, a portal site is "a site that the owner positions as an entrance to other sites on the internet."
We've built everything from simple e-commerce apps to applications to manage complex phyical workflows in a manufacturing environment to apps monitoring real-time testing of hardware. The sweet-spot is still Ajax-ified database babysitters, but portals aren't too hard to deal with. I was able to recreate Google's dynamic desktop in about an hour using standard Prototype and Script.aculo.us, and coupled with Rails' support for Ajax, a full portal is only a little farther away.
