Multiple Class Files in Zephir Extension

Question

I am doing some experiments with Phalcon Zephir to see how well it can convert some of my libraries to PHP extensions.

I have two PHP classes, each of which is already defined in its own file: Zephir notes are very clear that this should be so.

trienode.zep

namespace tries;

class trienode
{
    public children;

    public valueNode = false;

    public value = null;

    public function __construct()
    {
        let this->children = [];
    }
}

and

trie.zep

namespace tries;

class trie {

    private trie;

    public function __construct() {
        let this->trie = new trienode();
    }
}

But whenever I try to compile classes with zephir compile, I get

Warning: Class "trienode" does not exist at compile time  in /home/vagrant/ext/tries/tries/trie.zep on 8 [nonexistent-class]

            let this->trie = new trienode();
    ---------------------------------------^

(and if I continue the build process and install the resulting .so file, these are errors when I try to use it from a PHP script)

<?php

namespace tries;

$test = new trie;

gives

PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib/php5/20121212/tries.so' - /usr/lib/php5/20121212/tries.so: undefined symbol: zephir_tries_trie_init in Unknown on line 0
PHP Fatal error:  Class 'tries\trie' not found in /home/vagrant/triesTest.php on line 5

I looked at Zephir documentation and various blog entries, but cannot find examples of creating an extension containing more than one class file.

let this->trie = new tries\trienode();
//                   ^^^^^^
