xcin start problem

[kylezhou]

after emerging xcin, I lauched xcin in Konsole (KDE), but always got errors.
1)
#xcin
XCIN (Chinese XIM server) version 2.5.3-pre3.
(module ver: 20010918, syscin ver: 20000210).
(use "-h" option for help)

xcin: locale "zh_CN" encoding "gb18030"
xcin: error: /etc/xcinrc:

2)

3)
# LANG=zh_CN.gbk xcin
