Hi Morgan,

The only time that I've seen that error, it has been caused by duplicate
extension loading.  If you've already removed duplicates from your
extensions.ini file, set up a page with the phpinfo() function so you
can see what other .ini file directories might be in the search path.

You might even get some good information from this command:

truss -f -a -s 256 -o /tmp/php-cli.log php -v

Once the process exits, check the /tmp/php-cli.log file and search for
"zlib" in it.  You might see the zlib extension loaded more than once
and be able to determine what .ini file is causing the duplication.

Hope that helps,
