Horde 3 uses different libraries than horde 4. Somewhere between Horde3-cvs 
and Horde-git / Horde 4 there was a name change. What was RDO before is now 
Horde_Rdo and so on. So even if you had a cvs horde 3 version of some module, 
there should be no conflicts. In fact, it doesn't matter because the git 
version of Horde 4 doesn't install to peardir. I even have a test server where 
horde 4 and horde 4 (git) are running without interference.
