This might help. Saw a few posts when trying to get Kerberos from MIT compiled up on AIX 5.2/5.3
I had a problem with libs – couldn’t find shared libs. I added this to config/shlib.conf
Its the -brtl that makes the linker see the .so files as well as the .a files. Dont know why its not added already – but anyway thats what I did. I also had to load the AIX Berkley Embedded DB package – I just loaded the RPM from the IBM http://www-03.ibm.com/systems/power/software/aix/linux/toolbox/download.html toolbox
Once loaded – the whole thing ran and I was able to use the kinit.c source for an embedded Documentum application to authenticate against an Active Directory.
A bit obscure but it may save you a couple of days getting Kerberos compiled and running on AIX
