RFC822 problem

[Damir Dezeljin]

Is there a way to disable this feture in IMP-1.3.7-CVS without
recompiling and reinstaling PHP manualy - I user RH-7.1 and I don't want
to install any other packages if it isn't .rpm???

The problem:
Warning: Failed opening 'Mail/RFC822.php' for inclusion
(include_path='.:/usr/share/php') in
/var/www/dezo/horde/imp/lib/../../lib/MIME.php on line 97
