Installation error with 'zlib'

When trying to install on Ubuntu 13.04 with default zlib installed I get the error:

I did find a solution on stackoverflow that allowed me to successfully install...but I'm confused why this wouldn't just work by default.

Thanks for making the program available!

I fixed the makefile to have the -lz flag at the end of the line. Thanks!

Great, thanks.
