PEAR - Yes
Recent PEAR - Yes
Mail - Yes
Log - No
Make sure you are using a version of PEAR which includes the Log classes, or that you have installed the Log package seperately. See the INSTALL file for instructions on installing Log.
DB - Yes
Net_Socket - Yes
Date - No
Horde requires the Date_Calc class for Kronolith to calculate dates.
HTML_Common/HTML_Select - No
Horde requires the HTML_Common and HTML_Select classes only for Kronolith 1.0 to display forms correctly.
Unknown error: main(): Failed opening 'Mail/mimeDecode.php' for inclusion (include_path='.:/usr/share/pear') (/usr/share/toaster/htdocs/horde/test.php:194)

You need to install the pear libraries refernced by Horde/IMP scripts. From the command line try something like 'pear install HTML_Common'

You'll also need HTML_Form and HTML_Select_Common.
