It seems you're right. afni-ver returns the following
Precompiled binary Debian=x86_64-1-gnu: June 12 2017 (Version-16.2.07~dfsg.1-5~nd12.04+1
I'm not sure to what the June 12 2017 refers. When my afni commands were still working, I verified that the 3dclustsim being run by my current installed AFNI was from 2014(hence my need for an updated version for the new 2015 add ons). The output for afni_system_check.py -check_al is below. Thank you.
