We are waiting for the community of users of R on AIX to put in the 
resources needed to make this happen. 

We receive little help from AIX users of R (with the shining exception of 
Ei-ji Nakama), for example I cannot recall a single alpha/beta test report 
on that platform, and I would hope to recall several a year.  So it is 
mainly due to inspired guesswork that R compiles on AIX.

Given that apparently we are able to build libRlapack as a shared library 
on AIX, the same recipe should work for libR.  (As far as I recall the 
difficulty is getting a suitable export file from the motly collection of 
objects that make up this shared library.)  But this really needs someone 
with detailed knowledge of AIX linkers to tackle it, as quite possibly 
there is a better approach.
