As far as I can see, I am using the official one: http://www.zlib.net/zlib123-dll.zip
Then I do not see why scons can not locate zlib. Things are fine here.
I got the cmake version to build, so this is not critical. I think the chances are probably high that it's scons tool itself which is broken. After all, I am just using some random nightly build. For instance, "scons -h" does not work as it should: It does not print help, but tries to compile. (Except if I run it in a directory without any scons files, where it works, strangely enough)
This is something particular about scons. It processes the SConstruct file, collect usage information, before it shows any help information. In your case, scons stops at zlib step so it will never go to the show help stage. I guess this is something I can work on. Bo
