I'm having a problem when I try to compile APACHE + PHP + IMAP .

The OS that I using is:
2.4.2-SGI_XFS_1.0 #1 Fri Apr 27 19:30:49 CDT 2001 i
686 unknown
apache 1.3.20
php 4.0.6
imap-4.7c / imap-4.7a / imap-2001.BETA.SNAP-0107221451

Here is the problem

When I try to compile doing this: (here is the exact commands)
Firts I compile the apache with all modules (just in case)
cd apache_1.3.20
./configure --prefix=/usr/local/apache --enable-module=all
make
make install

and php with this
./configure --with-apxs --with-imap=../imap-4.7c --with-mysql --with-ldap
make
make install
/usr/local/apache/bin/apachectl start

Syntax error on line 762 of /usr/local/apache/conf/httpd.conf:
Cannot load /usr/local/php-4.0.6/libs/libphp4.so into server: /usr/local/php-4.0.6/libs/libphp4.so: undefined symbol: mxdriver
./apachectl start: httpd could not be started


I tried this with a lot a diferents source imap and still make me the same.

I trie puting that and still doesn't work
export LDFLAGS="-L/usr/kerberos/lib -lkrb5 -lgssapi_krb5 -lpam" 
ldconfig BEFOR compiling Apache. 

Any assistance would be of great help! 

Thank
