[Buildroot] Problem compiling busybox with libpam

[Spider]

I was using buildroot to compile busybox and got the following error
when I add libpam using "make busybox-menuconfig".  (The output is
below).
How can I get libpam to compile without this errors? If I "make clean"
and remake everything from scratch will it work? (I wil try this
tomorrow because of the time to compile and fear of configuration files changes)

I searched for a similar problem but didnt find anything on
documentation. Do I need to manually supply security/pam_appl.h and
security/pam_misc.h? Where to find them?

(make busybox-menuconfig ... )
