Description:
------------
Hello,

I have tried using both svn-0.2 and the CVS version, but both appear to have this problem.  I am running PHP 5.2.3, apr 1.2.9, apr-util 1.2.8, and subversion 1.4.3 under apache 2 (all from MacPorts), and when I try to dl('svn.so') I get the following in my apache error log:

dyld: NSLinkModule() error
dyld: Symbol not found: _empty_string
  Referenced from: ./lib/svn.so
  Expected in: flat namespace

[Sun Jul 22 11:15:20 2007] [notice] child pid 4641 exit signal Trace/BPT trap (5)

I'm not sure if this is an error with the MacPorts PHP package or with svn, but I suspect the latter.  

Reproduce code:
---------------
<?php

dl('lib/svn.so');
print "Loaded svn OK";

?>

Expected result:
----------------
Loaded svn OK

Actual result:
--------------
In Apache error log:
dyld: NSLinkModule() error
dyld: Symbol not found: _empty_string
  Referenced from: ./lib/svn.so
  Expected in: flat namespace
