hi, why this happenning when execute #apachectl stop #ldd mod_dav_svn.so libsvn_repos-1.so.0 => /root/subversion-1.6.9/subversion-1.6.9/subversion/libsvn_repos/.libs/libsvn_repos-1.so.0 (0x00c98000) libsvn_fs-1.so.0 => /root/subversion-1.6.9/subversion-1.6.9/subversion/libsvn_fs/.libs/l

why mod_dav_svn.so is not presented after I have run make
