Some programs, such as Mozilla, require autoconf-2.13 instead of newer versions. So, a system for allowing both versions to co-exist needs to be found. Currently, I'm installing autoconf-2.13 to /boot/apps/autoconf-2.13 and running it as a full path /boot/apps/autoconf-2.13 --macro-dir=/boot/apps/autoconf-2.13/share (or share/autoconf) It works, but does anyone have any better suggestions?
