The chance the perl is older than 5.8.7 is very high. This is a version of
AIX anno 2007.
Is perl 5.8.7+ needed during the use of bison, or only for the make. I am
attempting to have a version packaged that will go back in time as much as
possible.
oslevel -s:5300-07-01-0748
perl -v:
This is perl, v5.8.2 built for aix-thread-multi
(with 3 registered patches, see perl -V for more detail)
Tried setting the environment myself (hoping...)

So, I conclude your suspicions are correct. Now how to correct?
