[Serusers] problem with loading compiled radius modules

I had the same error msgs when I load the radius_acc modules the following is the error msgs [root@md benny]# /usr/sbin/ser restart 0(3699) ERROR: load_module: could not open module </usr/lib/ser/modules/radius_ acc.so>: libradiusclient.so.0: cannot open shared object file: No such file or d irectory 0(3699) parse error (25,13-48): failed to load module ERROR: bad config file (1 errors) [root@md benny]# and I check that the radius_acc.so is in /usr/lib/ser/modules and the libradiusclient.so.0 is also in /usr/local/lib as it is stated in the Makefile. Where is the error came from? Have any one successfully implement it?
