Problem installing IMAP

I am having a problem getting php4.0.4pl1 to work will imap on my Mandrake 7.2 linux system. I am configuriging the system using the following configure options :- ./configure --with-apxs \ --with-oci8 \ --without-mysql \ --with-pgsql \ --with-imap \ --with-ldap I have followed the instructions about c-client and have tried upgrading to imap-2000c and even imap-2001beta packages from ftp.cac.washington.edu/imap/ Evering seems to compile and install OK but when I try to start apache I get the following message :- Cannot load /etc/httpd/modules/libphp4.so into server: /etc/httpd/modules/libphp4.so: undefined symbol: mxdriver Any help would be appreciated. -- Thanks, Richard
