I got this error while trying  to build libpng in MinGW.

I do have zlib installed on my system. Anyone else encountered this error?

I think it's my fault. Does this change solve the problem for you?

Yes it does. The package builds fine now. However I do suspect that the actual reason might be because of the missing line

     C:\MinGW\   /usr/local

in my fstab file inside /etc (C:\MinGW\msys\1.0\etc) directory. 

It is possible that libpng didn't find the installed libraries because of the incorrect configuration.
