I have upgraded my php to 4.1.2 -so when I try to install the UPDATE3 rpm's for esmith 5.1.2 I get 
        php >= 4.1.0 is needed by horde-2.0-4es
        php >= 4.1.0 is needed by imp-3.0-3es
        php >= 4.1.0 is needed by turba-1.0-5es
        php-imap >= 4.1.0 is needed by imp-3.0-3es
I can I fix this? Can I just force the installation?
