You could setup a Gentoo / Arch Linux and build/install the packages.
Unless AIX doesn't open up its packaging infrastructure (and i'm not referring to RPM/yum.sh disaster) to outside FOSS contributor's, Linux will continue to be the platform of choice.
If you are up for real exploration, i'd like to draw your attention pf 'pkgsrc' (portable package build system)

gcc toolchain, still needs to be installed from that abomination called RPM/yum.

Log Stash
You are going to need JDK 8 and JRuby 9.1

Kibana
you are going to build node.JS

and then

Guess one needs to put in some time and effort, but it's doable !
