Error while sending new mail

[Ondra Zima]

Hi all,
I install Horde and IMP from CVS and if I want to create and send
message, IMP only show this:

Warning: Failed opening 'Mail/rfc822.php' for inclusion
(include_path='/usr/local/lib/php') in
/var/www/horde/imp/../lib/MIME.php on line 107

Fatal error: Undefined class name 'mail_rfc822' in
/var/www/horde/imp/../lib/MIME.php on line 109

Where is 'rfc822.php'? And further where is 'Log.php' which is needed
for action loging?
This files are not in CVS.
