Javascript Error: tinyMCE not defined

I am running Drupal 5.3. I have tinyMCE 2.1.2 installed. I have followed installation instructions carefully several times. tinyMCE editor will not load, and FireFox reports a javascript error -- tinyMCE not defined. The tinyMCE javascript file is loaded by my pages with the following tag:

<script type="text/javascript" src="/sd/sites/all/modules/drupal-contrib/tinymce/tinymce/jscripts/tiny_mce/tiny_mce.js"></script>

This tag correctly points to the js file. I do have a print $scripts in my page.tpl.php.

The error is triggered by this script:

<script type="text/javascript">
 tinyMCE.init({
 mode : "none",
 theme : "advanced",
 relative_urls : false,
 document_base_url : "/sd/",
