I couldn't get it to install as a library, either. So, I've modified ArduinoJson to work with Galileo. You have to drop the contents of this zip into your project (ie, same level as your *.ino).

The library is very much architecture independent. It works well with any Arduino board. The issue is with the version of the IDE.
I contacted the author and he provided me a new version of the library with the old layout compatible with Arduino 1.5.3 and it works perfect.
No changes on the code, just change on the library layout.
This is a good example of elegant implementation of an JSON parser.
