Comment(by jonas@…):

 hmmm that's interesting. I thought zlib was already pulled in by Qt, but
 maybe the cocoa version doesn't do so... That wuold also explain why I
 can't reproduce the problem here on Leopard. (qt4-mac builds per default
 the cocoa variant on snow leopard, since the carbon variant isn't 64 bit
 ready)

 Your patch seems a bit hacky though. Could you please try to add zlib to
 SYS_LIBS, say
 {{{
 - puts $confFD "SYS_LIBS = -L${prefix}/lib"
 + # snow leopard seems to need zlib explicitly, see #23272
 + puts $confFD "SYS_LIBS = -L${prefix}/lib -lz"
 }}}

 If this works, add zlib as additional dependency and feel free to commit,
 thanks.
