I've looked at Debian, Fedora, Ubuntu, openSuse: their alpine packages have the same imperfection (they depend on libpam), but PLD seems to have correctly patched the build process os that their alpine doesn't depend on libpam:

As one can see from their spec-file, they used the solution described here as well -- http://talk.maemo.org/showthread.php?p=90746#post90746 :

"Regarding the PAM issue, I agree with the suggestion to build using slx or lnx as the c-client target. lnx may be a better choice than slx; <...>

Alternatively, you could just supply dummy PAM modules if you don't want to override the configure script. It only matters for the POP3 and IMAP servers;"
