Locale woes

Greetings Forumers!

I've been fighting a locale problem on a v490 running Solaris 10 u4 (8/07). When I login to the system, I get several "locale" error messages:

user1's password:

You have mail.
couldn't set locale correctly
couldn't set locale correctly

$

I have tried modifying /etc/default/init several times but the error message continues.

What else can I check to resolve this issue?

Thanks In Advance!!!

SOLVED: I found this blog entry and checked my system for the following packages:

SUNWi1cs
SUNWi15cs
SUNWnamos

I was missing the SUNWnamos package so I installed it and now I don't get that error message.
