problems compiling php+imap with apache

Hi. I'm trying to install apache with php4 and imap (c-client) on RedHat7.1 . C-client compiles fine. PHP (4.0.6) always compiles fine (with --with-imap or without it). Apache (1.3.9) compiles (and works) fine only if PHP was compiled WITHOUT imap. If PHP was compiled with imap apache does not compile successfully (problems with imap libraries): ... modules/php4/libphp4.a(php_imap.o): In function `mail_close_it': /root/soft/php-4.0.6/ext/imap/php_imap.c:190: undefined reference to `mail_close_full' modules/php4/libphp4.a(php_imap.o): In function `mail_newfolderobjectlist': /root/soft/php-4.0.6/ext/imap/php_imap.c:250: undefined reference to `fs_get' modules/php4/libphp4.a(php_imap.o): In function `mail_free_foblist': /root/soft/php-4.0.6/ext/imap/php_imap.c:263: undefined reference to `fs_give' modules/php4/libphp4.a(php_imap.o): In function `mail_newerrorlist': /root/soft/php-4.0.6/ext/imap/php_imap.c:277: undefined reference to `fs_get' modules/php4/libphp4.a(php_imap.o): In function `mail_free_errorlist': /root/soft/php-4.0.6/ext/imap/php_imap.c:288: undefined reference to `fs_give' modules/php4/libphp4.a(php_imap.o): In function `php_rshutdown_imap': /root/soft/php-4.0.6/ext/imap/php_imap.c:330: undefined reference to `mail_free_stringlist' modules/php4/libphp4.a(php_imap.o): In function `mail_newmessagelist': /root/soft/php-4.0.6/ext/imap/php_imap.c:356: undefined reference to `fs_get' modules/php4/libphp4.a(php_imap.o): In function `php_minit_imap': /root/soft/php-4.0.6/ext/imap/php_imap.c:437: undefined reference to `unixdriver' /root/soft/php-4.0.6/ext/imap/php_imap.c:437: undefined reference to `mail_link' /root/soft/php-4.0.6/ext/imap/php_imap.c:439: undefined reference to `imapdriver' ...
