[horde] Install Horde from Git

[Jonathan Rogers]

I am trying to install Horde from the Git repository, but have encountered
great difficulty. After much frustration, I did finally manage to get the
framework libraries installed properly. However, now the test.php script
just gives me:
------------------------------------------------
A fatal error has occurred
Bad log level
Details have been logged for the administrator.
------------------------------------------------

In the web server error log, I only see: 
------------------------------------------------
[Fri Mar 26 05:51:51 2010] [error] [client 71.68.98.66] PHP Fatal error: 
Exception thrown without a stack frame in Unknown on line 0
[Fri Mar 26 05:51:51 2010] [error] [client 71.68.98.66] PHP Stack trace:
[Fri Mar 26 05:51:51 2010] [error] [client 71.68.98.66] PHP   1.
Horde::fatal() /usr/share/php/Horde.php:0
------------------------------------------------

I haven't seen anything so far to indicate where the log level is set or
why it's bad. I have "error_reporting = E_ALL & ~E_NOTICE" in my php.ini,
but I'm pretty sure that's not what the error is referring to. I haven't
found any log level setting in a configuration file so far, so any pointers
would be helpful.
