[chora] chora not including PEAR.php

[Rob S.i.k.l.o.s]

Hi Guys,

I'm having a problem with Chora not including PEAR.php (using latest HEAD 
horde, framework, and chora from CVS).

I get errors like:

Notice: Use of undefined constant OS_WINDOWS - assumed 'OS_WINDOWS' in 
/var/www/cvs/horde/chora/cvsgraph.php on line 69

It may have something to do with my configuration, in that some files which 
are typically loaded aren't:
- $conf['auth']['driver'] = 'auto';
- I don't display the navigation tree

Anyways, my temporary workaround was to just include PEAR.php from 
chora/lib/base.php.

Cheers,

Rob.
