Fatal error - Help install horde 1.3.5-cvs and IMP 2.3.7-cvs

[Darci Antônio Tartari]

    I am running Horde 1.2.3/IMP 2.2.3 in a FreeBSD 4.2 machine togher with a 
mysql 3.22.32. It´s working very well as mail server for 150 clients.  Now 
people are asking for an utility like turba, so I decided to install horde 
1.3.5-cvs, imp 2.3.7-cvs and Turba 0.0.3-cvs. 

    I am trying to run in parallel this new version with the old one to make 
sure it will work good. So a made an upgrade for php 4.0.4p1 to 4.0.6 with pear 
and I install pear at /usr/local/lib/phplib/pear (The most recent one). I put 
the new version of horde at  /horde13/horde of my webroot. The old version of 
imp is running today as my webroot.

    The old version of horde/imp is still working good, but the new version 
produce a fatal error as you can see bellow. 

   
Fatal error: Failed opening required 'PEAR.php'
(include_path=''/usr/local/lib/phplib:.:/horde/webcal:/horde/imp/admin:/usr/loca
l/www/data/nuke/html:/usr/local/lib/phplib/pear'') in
/usr/local/share/doc/apache/horde/imp/horde13/horde/lib/Registry.php on line 4


Is there anybody who could give a tip ? 

Thanks a lot!
