I can't emerge pam

this is the output I get:

Knoppix pam # emerge pam

all these problems started after an emerge -u world

since I have unmerged pam and pam-login I can't login to my system
prior to this, after pressing return at the user prompt I got an ld_config 
error and got back to the prompt.

any ideas?

Thank you in advance
