[openbox] openbox 3.5 startup problem

[Fred]

Hello,
I am trying to upgrade from openbox-3.4 from Debian-6.0 packages to 
3.5.  I have compiled from source and installed.  Openbox doesn't run. 
The xdm.log file shows openbox reported it couldn't find 
libobrender.so.27.  That file exists in /usr/local/lib.  Dpkg shows the 
libobrender21 package is installed ok.  How can I make openbox-3.5 happy?
Debian 6.0 (sparc)
Best regards,
Fred
