How to activate IMAP with Horde? (imap_utf7_encode problem)

This means dynamic modules? I compiled Apache and PHP static.
If not: How to install php-imap module???

When I try to include dynamic extensions like imap.sl Apache complains, 
since I compiled Apache statically. 

The error when calling IMP is:

Fatal error: Call to undefined function: imap_utf7_encode() in /opt/horde/lib/horde.lib on line 440

My Configuration:
* apache	1.3.12
* php		4.0.2
* horde		1.2.3 
* imp		2.2.3

The output of test.php3 is "PHP Module Capabilities     IMAP Support: No" 


phpinfo() displays:

Loaded Modules                    mod_php4, mod_setenvif, mod_auth, mod_access, mod_alias, mod_userdir,
                                  mod_actions, mod_imap, mod_asis, mod_cgi, mod_dir, mod_autoindex,
                                  mod_include, mod_status, mod_negotiation, mod_mime, mod_log_config,
                                  mod_env, http_core

=> imap is included in PHP!?

Any help appreciated,
