I have come a bit further, but not found a solution.

via IRC i was pointed at this "rejected" bug-report:
http://redmine.ruby-lang.org/issues/show/1157

However, regardless of whether I re-run configure with
CFLAGS=/usr/local/include (where zlib.h is located), or not during make the
flag -I/usr/include/local is not added to the test, so make "fails" in that
zlib.rb and/or Makefile in ./ext/zlib does not get made.

for ./ext/zlib/mkmf.log

have_header: checking for zlib.h... -------------------- no

"cc -qlanglvl=extc89 -E -I../../.ext/include/powerpc-aix5.3.0.0
-I../.././include -I../.././ext/zlib  -D_LARGE_FILES=1  -I/usr/lib/include
-g  conftest.c > conftest.i"
"conftest.c", line 3.10: 1506-296 (S) #include file <zlib.h> not found.
checked program was:
/* begin */
1: #include "ruby.h"
2:
3: #include <zlib.h>
/* end */

If I am missing something - not obvious to me - please suggest!
