>Description:
It is a bit like for OSF1 as described in PR 31489
sysutils/fam will not compile even after I fixed some errors. I just stopped to 
do so and marked gamin as FAM_DEFAULT in mk/platform/AIX.mk like it was done 
for OSF1
>How-To-Repeat:

>Fix:
add to mk/platform/AIX.mk:

# sysutils/fam is not usable on AIX.
FAM_DEFAULT?=           gamin
