I experience a similar problem to already reported in closed http://bugs.gentoo.org/161813 This time the problem concerns media-libs/netpbm-10.46.00-r1. Emerging netpbm fails with a linking error, probably due to missing -lz. Reemerging libpng did not help.

Attach build.log (probably config.log too).
Created attachment 209768 [details] build.log
I attached the build.log. There seems to be no config.log. At least the following returns nothing: find /var/tmp/portage/media-libs/netpbm-10.46.00-r1 -name config.log Did I miss something?
The problem seems to be the following: 1) In the Makefile: ifeq ($(shell libpng-config --version),) PNGLIB_LIBOPTS = $(shell $(LIBOPT) $(LIBOPTR) $(PNGLIB) $(ZLIB)) else PNGLIB_LIBOPTS = $(shell libpng-config --ldflags) endif which means that ZLIB is only used when the flags cannot be obtained using "libpng-config --ldflags". 2) At the same time on my machine: marcade other # libpng-config --ldflags -L/usr/lib64 -lpng12 marcade other # ldd /usr/lib64/libpng12.so linux-vdso.so.1 => (0x00007fff1c1ff000) libm.so.6 => /lib/libm.so.6 (0x00007fe534169000) libc.so.6 => /lib/libc.so.6 (0x00007fe533e14000) /lib64/ld-linux-x86-64.so.2 (0x00007fe534658000) which means that libpng does not really need zlib by itself. 3) The linker error comes from pnmtopng.c itself: pnmtopng.c:(.text+0x4719): undefined reference to `zlibVersion' 4) So it really seems to be an upstream problem, do you confirm?
