samba - Sep 2005 - Samba --with-ads on AIX compile error

I need to compile ads into Samba on AIX 5.2. The compile fails in the 
krb5 segment with:

Compiling libsmb/clikrb5.c
libsmb/clikrb5.c:123: #error UNKNOWN_CREATE_KEY_FUNCTIONS
libsmb/clikrb5.c:160: #error UNKNOWN_GET_ENCTYPES_FUNCTIONS
make: 1254-004 The error code from the last command is 1.

Does anyone have a remedy for this?

Thank you
