Reviving pkgsrc for (modern-ish) AIX

[Brian Callahan <bcallah%posteo.net@localhost>]

Hi all --

Thomas alerted me to the existence of a thread based on my blog post 
prior to my joining the list, so apologies for creating a new thread.

Thanks for the hints. I'll note that I did not modify my 
/opt/pkg/etc/mk.conf other than what the diff from the blog post adds 
(and I also added MAKE_JOBS=3). I am away the next few days but I will 
try some of these out when I am back. Thomas also gave me some hints to 
fix the cosmetic AIX 2 vs AIX 7.2 issue which I also hope to fix when I 
am back.

Thanks.

~Brian
