[Serusers] can not open dictionary from freeradiusd!

[zhu lizhong]

hello, guys:
I installed freeradiusd and SER. now, i want to connect the two
together. the problme is that when i include dictionary.ser in
raddb/dictionary, and run radiusd -X, then the messages came out as
follow:
------------------------------------- 
read_config_files:  reading dictionary
Errors reading dictionary: dict_init:
/usr/local/etc/raddb/dictionary[14]: Couldn't open dictionary "
/usr/local/share/freeradius/dictionary": No such file or directory
Errors reading radiusd.conf
--------------------------------------
any one knows how to solve it, please give me hints. thanks lot!
