PhpApi problem

[Marcus Spurkel]

I'm getting a "undefined symbol: empty_string in Unknown on line 0" 
error when I try to load libphp_MapGuideApi.so into PHP.  It's probably 
because I'm trying to use PHP 5.1.4, which has some significant changes 
to the Zend code (among other things).  I tried replacing Oem/php with 
the latest source version from php.net and then re-making PhpApi but 
that generated a ton of errors.  Is there an easy way to get it to run 
with PHP 5.1.4, or will I need to back my version down to 5.0.5?
