where did the php5 extensions go?

[Jeff D. Hamann]

I've just installed the mod_php5 port (successfully) and need to start 
turning on some of the extensions. I'm working on:

FreeBSD qqq.qqq.com 6.0-RELEASE FreeBSD 6.0-RELEASE #2: Sun Nov 27 14:07:55 
PST 2005     qwerty at qqq.qqq.com:/usr/obj/usr/src/sys/GENERIC  amd64

and can't seem to locate where the extensions are. I see the files to build 
the extensions are in the ports tree:

bobby# pwd
/usr/ports/www/mod_php5/work/php-5.0.5/ext
bobby# ls -la
total 180
drwxr-xr-x  82 root  wheel  1536 Dec  6 08:23 .
drwxr-xr-x  18 root  wheel  2560 Dec  6 08:24 ..
drwxr-xr-x   2 root  wheel   512 Sep  5 04:15 curl
drwxr-xr-x   6 root  wheel  1024 Sep  5 04:15 dba
drwxr-xr-x   3 root  wheel   512 Sep  5 04:15 dbase
drwxr-xr-x   3 root  wheel  1024 Sep  5 04:15 dbx
drwxr-xr-x   3 root  wheel   512 Sep  5 04:15 dio
...blah, blah, blah...
drwxr-xr-x   3 root  wheel   512 Sep  5 04:15 mhash
drwxr-xr-x   2 root  wheel   512 Sep  5 04:15 mime_magic
drwxr-xr-x   3 root  wheel   512 Sep  5 04:15 ming
bobby#


but I don't see where the final *.so files are located and when I add 
(uncomment) the extension (the php_dbase.so in this case) in the 
/usr/local/etc/php.ini file, run a small <?phpinfo();?> script, I get the 
standard stuff without any extensions.

Is there something I'm missing?

Thanks,
Jeff.
