I ran into this same problem.  I attempted to fix all the errors in the 
Horde code (you have to change the way functions return variables - do a 
google search), but I gave up after a while because I still couldn't make 
it actually work.

I was attempting to add a new Webmail server that ran Debian Etch (old 
servers were Debian Sarge).  Luckily, Etch still had PHP4 packages, so I 
just installed PHP4 instead.  When I finally upgraded to Horde3/IMP4, I 
also upgraded to PHP5 at the same time.  Again, this is really easy with 
Debian.

Everyone else gave you good advice -- only Horde3 supports PHP5.
