You need Zlib. Get it from ps2dev's svn server.

i also got that, somethimes it happens even with the libarys installed

make sure that you have Zlib installed correctly, if need be, just redownload it from the SVN and install it again. Be sure to follow the instuctions in the README.PSP for Zlib on how to install it, that and any other lib.
