I suppose you have a Windows machine from the library names. I'll admit 
I have no idea where extconf.rb looks for libraries by default there or 
how it does it. Do you have Zlib somewhere on your computer (e.g. the 
files it's looking for) at all, by the way?

When trying to compile extensions, you might want to use the mingw32 
version of ruby instead of the mswin32 one the one-click-installer uses. 
Mingw and MSYS work a quite bit more automagically than a VC++ one, that 
is, unless you bought or otherwise came to own Visual Studio.

And just by the way, the one-click-installer comes Ruby 1.8, which has a 
working Zlib in the standard library - notice the RAA page mentioning 
the standalone module is deprecated.
