compiling after proxy_auth_patch

Hi,

after I applied the proxy_auth patch, squid won´t compile anymore... i
get an error from a few modules, like client_side.c, comm.c, main.c,
every time an undefined reference to some function i.e.
authenticateStart, authenticateServers.... any clue on this one?
