In particular, there isn't any sort of PHP VM that we could meaningfully 
target. We'd be compiling Ruby to PHP, at best. JRuby doesn't compile Ruby to 
Java, it compiles Ruby to JVM bytecode.

The rest of this is true, also:

The "rich set of libraries" is the only benefit I can see for PHP, and I'm 
very skeptical -- not just of quantity, but of quality.
