I suspect the last line is what you're looking for.

You're in luck, I have a little list I keep that I refer to every time I 
(re-)install the PHP port:

bzip2
ctype
curl
dbx
dio
domxml
exif
ftp
gd
gdbm
gettext
gmp
iconv
imap
mbstring
mcal
mysql
ncurses
openldap
openssl
pcre
posix
pspell
session
shmop
snmp
sockets
sysvsem
sysvshm
unixodbc
wddx
xml
yp
zlib

And, just for completion's sake, here's the relevant output from
phpinfo():

'./configure' '--enable-versioning' '--enable-memory-limit'
'--with-layout=GNU' '--with-zlib-dir=/usr' '--disable-all'

Thanks for looking into this, I'm definitely out of my depth here!
