[Serusers] Acc with Radius support failed.

I tried to load SER with Radius Account support. SER failed to start with the following error message: 0(30753) ERROR: load_module: could not open module </usr/local/lib/ser/modules/acc.so>: libradiusclient.so.0: cannot open shared object file: No such file or directory 0(30753) parse error (42,13-47): failed to load module 0(30753) set_mod_param_regex: No module matching acc found | 0(30753) parse error (54,32-33): Can't set module parameter 0(30753) set_mod_param_regex: No module matching acc found | 0(30753) parse error (58,33-34): Can't set module parameter 0(30753) set_mod_param_regex: No module matching acc found | 0(30753) parse error (59,31-32): Can't set module parameter 0(30753) set_mod_param_regex: No module matching acc found | 0(30753) parse error (62,31-32): Can't set module parameter 0(30753) set_mod_param_regex: No module matching acc found | 0(30753) parse error (64,42-43): Can't set module parameter 0(30753) set_mod_param_regex: No module matching acc found | 0(30753) parse error (65,41-42): Can't set module parameter 0(30753) set_mod_param_regex: No module matching acc found | 0(30753) parse error (66,58-59): Can't set module parameter 0(30753) set_mod_param_regex: No module matching acc found | 0(30753) parse error (67,29-30): Can't set module parameter 0(30753) set_mod_param_regex: No module matching acc found | 0(30753) parse error (68,35-36): Can't set module parameter 0(30753) set_mod_param_regex: No module matching acc found | 0(30753) parse error (69,37-38): Can't set module parameter ERROR: bad config file (11 errors) I cannot figure out what went wrong. I installed my SER with the latest CVS. I also have radiusclient and freeradius installed on the same machine. Any idea? Younger Wang
