I read all the posts on zlib but cannot find an answer … .  
I installed ruby on AIX 4.3.3 from tar.gz. My ext/zlib contains zlib.o  
and zlib.so. make test produces no errors. However, when I run ruby  
setup.rb from rubygems install, I get “no such file …”

Please help me install zlib in the proper place.
