Correct, squid is not an NTLMSSP client.

Samba has an NTLMSSP client and server implementation, that can be used
by external programs. The interface is currently not the best, but you
can call ntlm_auth over stdio to do the job. (This presumes you wish to
modify the source to wget or apt-get).
This is in Samba 3.0.2, of which we just released rc2.
