is this related to the second problem?  (It's been a while since I tested
on AIX - early 2002 iirc - but I don't recall a problem getting it to
build and run).

That's easy to explain: ncurses and AIX terminfo are different formats.
There are alternate Caps.* files that I've made which can be used when
compiling ncurses to adapt to some other formats, including AIX (this
one I recall constructing for someone else who tested it).  See the
--with-caps configure option.
