You probably don’t have the zlib development library installed. Ensure
both the runtime and development library are installed.

this problems also happen in hpux(11.23, 11.31).

ruby installer doesn’t distinguish between sl and so extension.

I need to make all symbolic links from sl to so in /usr/local/lib/ruby/*
