[kudiejlq]

Hi,
I have met a problem when install sebverion 1.6.9 on RedHat ES 4.5.
 
I did things that INSTALL told me and the run
#./configure
#make
and there is no error message have been raised, but I can not find 
mod_dav_svn.so any where after make return successfully
 
what is the problem? 
 
thanks.
