Problem linking qpopper 404 on Trustix

[Gennaro Esposito]

Greetings
I'm an happy user of qpopper on a DEC OSF/1 platform. Now I'm moving all the e-mail services (SMTP and POP...IMAP will follows ;-) ) from that platform to an Intel/Trustix (a secured version of RH Linux: www.trustix.net) but I've experienced a problemd in the link phase of the poppassd generation. Trustix uses PAM as its user validation architecture and I'm using the shadow method.
Hereafter an abstract from the log generated by script command:

Well, I had a look in the poppassd.c and in the auth_user.c code and in the last one I've seen that the auth_user function is inside a nested #ifdef #else condition:
#ifdef SPEC_POP_AUTH
# ifndef USE_PAM
<....a lot of auth_user definition for various unix flavors that do not use PAM....>
# endif /* USE_PAM */
#else /* not SPEC_POP_AUTH */
< a definition of auth_user for systems that do not use shadow or others special auth...>
#endif /* SPEC_POP_AUTH */

In other words: I've both SPEC_POP_AUTH and USE_PAM defined, the dirst 'cause I use shadow and the second 'cause Trustix use PAM but this seems not allowed!
Is it a my fault? Or is it a poppassd coding error?
Please let me know asap
Thank you in advance
