./build php y

Reported for custombuild:

1) install c-client.
Debian:
apt-get install libc-client-dev

rpm systems (CentOS, fedora):
yum install libc-client libc-client-devel

Reported for CentOS 64-bit, also run:
yum install krb5-appl-clients.x86_64
yum install krb5-appl-servers.x86_64

2) Use this guide:
http://help.directadmin.com/item.php?id=252

to add these 2 lines to the bottom (don't forget the \ on the previous line before them)

--with-imap=/usr/lib/dovecot/imap \
--with-imap-ssl 

3) Then build php:
./build php n

and that's it.
