emacs-23.0.0.1 still does not cooperate with scim?

[big]

I have used scim as the chinese input program for emacs for a while and it worked fine,but that happened under ubuntu.However,when i changed to gentoo,i find something really strange.I never change my configuration of all programmes.scim still works fine with lots of other programmes,e.g.firefox,qterm and etc..only except emacs-21.Then,a CVS version of Emacs 23.0.0.1 is compiled natively.But scim won't be triggered either.The environment variables,e.g. LANG and LC_CTYPE are modified as zh_CN.gb2312 or zh_CN.gbk but without any success.So now i am really confused with the problem.I don't understand the reason that scim couldn't be activated.
Any suggestion will be welcome!

Sorry I don't know anything about SCIM. But I'm just wondering if you need to set your mule language environment in emacs?

With emacs, goto Options->Mule->Set Language Environment and choose your language. Ctrl-'\' will toggle input modes between your default language and your selected one.
