PHP4.0.2 --with-imap

Dear all, I am still new to this list (waving *hi* to everyone), and I have been playing with PHP4 since it was released. It has helped me to overcome a few web problems. Right now I would like to add imap features, and followed the installation guide. I use php4.0.2, apache 1.3.2 under FreeBSD 4.1 php (with imap) compiles fine, however, when I try to compile apache 1.3.2 with --activate-module=src/modules/php/phplib4.a the make generates the following error: .../libc-client4.so: undefined reference to 'mm_expunged' .../libc-client4.so: undefined reference to 'mm_diskerror' .../libc-client4.so: undefined reference to 'mm_lsub' and another bunch of those. the compilation ends with an error exit. I have tried a few things now (re-install the c-client, re-copying the so file, re-compiling php,...), but nothing seems to work. Any ideas? Thanks, Raoul
