Michael Felt added the comment:

it was, partly, about the technical details - but I feel I have found the key 
bits - /full/path/libNAME.a(libNAME.so) + dlflags RTLD_NOW + RTLD_MEMBER for 
"native" AIX support.

Additionally, a patch should not break what might be working for some (via 
google I read of suggestions for other languages, e.g., java, where .so members 
are extracted or installed side-by-side with the .a archive) - as the IBM 
run-rime loader also accepts/looks for both .a and .so. And/or for when 
/sbin/ldconfig is available. And when available, is this used as last case, or 
preferred?

Lastly, we cannot assume we will know the name of the member based on the name 
of the library. In many cases, e.g., libiconv.a the IBM names are shr.o, shr4.o 
and shr4_64.o - and these are the only member names unless GNU libiconv.a has 
been added (and then libconv.a also contains libiconv.so.2 (so version support 
is also desired!)) in both 32 and 64 bit mode.

One technical detail I have not been able to discover yet: how to determine 
whether in 32-bit or 64-bit mode. This will be important for libraries that 
have shr4.o and shr4_64.o as the members that need to be dlopened.

Lastly: about adding the "stanza": python is a new language for me. Any 
assistance with a patch - to keep it properly 'pythonized'

In short, I shall continue my studies/learning. Assistance from anyone wiser 
than me is welcome!
