Actually, in Prefix we already do wrap AIX' ld in sys-devel/binutils-config
to get the runpaths (the -blibpath argument) right.
At the moment I'm trying another thing to get full "soname" support,
both with and without libtool, using Import Files. There is an RFC
for the way I want to have shared libraries being created on AIX.
However, I'm still unsure if we actually should use the '# autoload' thingy,
but ignore the auto-dependency problem instead.
Additionally, for packages not using libtool, there's another ld wrapper in
sys-devel/native-cctools waiting for checkin here to support the '-soname' flag
known on ELF (Linux), creating the shared libraries according to above way.
Eventually, this second wrapper would be merged into binutils-config's wrapper.

Commenting on 'Readme.markdown' found there:
Why do you move '-blibpath' arguments to '-L' arguments?
IMO, the other way round would make more sense actually.
Why do you need 'rl' (relink) at all?

Haven't used/installed Ruby on any platform yet: What is 'rvm' ?

I fail to find that post you're referring to. Has it been within one
of the threads we already created together, and I've overlooked it?

For packages not aware of AIX at all:
How would this require their build systems to be patched?

In which context do you need this use case?
And how would you do that on Linux?
