[horde] horde imap-2007e php compilation issues

[Spyros Tsiolis]

Hello people,

Newbee here. Please don't shoot :-)
I've been trying to build horde groupware webmail edition for
quite some time now.
I've been banging my head against the wall these last days, because I
just cannot get past a specific point during the compilation session.

I've checked the Horde website time and again in case I missed anything.
I also checked all the libraries (Centos 5.4 "-devel" files that is),
in case I missed something there but to no avail.

Here's the configuration.
CentOS 5.4
PHP 5.2.11 or PHP 5.3.1 (both version complain about the same thing)
imap-2007e (from the cac.washington.edu site)

The Horde quickstart quide notes explicitly I should compile in the
"imap.tar.Z" file against php if I want Horde GW/WB edition behave 
properly and "play nice" with IMAP servers.

Here's the ./configure command (one line) :

--- 1-liner START ---
./configure --disable-all --with-apxs2=/usr/sbin/apxs --with-mysql --with-imap=/usr/local/imap-2007e --with-imap-ssl --with-gettext --with-mcrypt --with-iconv --enable-mbstring=all --enable-mbregex --with-zlib --with-gdbm --with-gd --enable-gd-native-ttf --with-openssl --disable-short-tags --with-freetype-dir=/usr/lib --with-kerberos --with-jpeg-dir=/usr/lib --with-png-dir=/usr/lib --enable-ctype --with-pcre-regex --enable-session --enable-xml --enable-libxml --enable-json
--- 1-liner END ---

Here's what the system complains time and again :

---
 -I/usr/include -g -O2 -fvisibility=hidden  -prefer-non-pic -c /usr/local/php-5.3.1/ext/imap/php_imap.c -o ext/imap/php_imap.lo
/usr/local/php-5.3.1/ext/imap/php_imap.c: In function 'zm_startup_imap':
/usr/local/php-5.3.1/ext/imap/php_imap.c:854: error: 'auth_gss' undeclared (first use in this function)
/usr/local/php-5.3.1/ext/imap/php_imap.c:854: error: (Each undeclared identifier is reported only once
/usr/local/php-5.3.1/ext/imap/php_imap.c:854: error: for each function it appears in.)
make: *** [ext/imap/php_imap.lo] Error 1
---

It comlplains about php_imap on the /usr/local/php-[version]/ext/imap
directory. However, I would think that this whould be redundant since I
use the UW imap (imap.tar.Z) archive.

Any help would be appreciated.
I apologize if this post is not indended for this list. However, I do 
believe this is the place to talk about it.
If it's not apologies and please ignore my message.

Thank you kindly for you time and hospitality,
