[horde] Horde 4 + MAMP

[Luis Felipe Marzagao/Andamentos]

Hello:

I'm trying to set up horde 4 with MAMP on Mac OS for testing purposes.

Everything seems to be ok. I could easily install horde and dependencies 
via 'pear instal ...'

After copying conf.php.dist to conf.php and setting proper parameters, I 
could successfully load horde and enter admin interface.

But just above horde menus and stuff I'm getting a lot of messages like 
these:

Warning: Invalid callback Horde::errorHandler, class 'Horde' not found 
in /Applications/MAMP/bin/php/php5.3.6/lib/php/PEAR/Config.php on line 650

Deprecated: Assigning the return value of new by reference is deprecated 
in /Applications/MAMP/bin/php/php5.3.6/lib/php/PEAR/Config.php on line 650

I have 'error_reporting  =  E_ALL' and 'display_errors = On' in my php.ini.

Why is it happening? What could be wrong? Any clues?

Thanks a lot
