the env lookup is still way more complicated than it needs to be:
	locale=${LC_ALL:-${LC_CTYPE:-${LANG}}}

it is not possible for these variables to be set but not exported unless an 
ebuild is doing it, and those are broken anyways.

the message should also reference an open bug report for people to follow so 
that this issue is properly fixed.  you cant drop warnings like this into 
places without a referenced bug # otherwise they can easily become outdated 
but no one knows how to easily determine "can this be punted yet".
