media-libs/libpng configure phase fails for the x32 part of the configuration process; zlib is properly detected for the x64 ABI when ABI_X86="32". Reproducible: Always Steps to Reproduce: 1. unpack a stage3 2. set ABI_X86="32" and ACCEPT_KEYWORDS="~amd64" and the default/linux/amd64/13.0/x32 profile 3. run emerge --sync and emerge -uDN world and ensure this step finishes without errors 4. emerge --oneshot libpng Actual Results: configure passes the x64 phase successfully, properly detecting zlib as installed, but fails at the x32 configure phase, with "configure: error: zlib not installed" Expected Results: zlib should install the x32 library on a default/linux/amd64/13.0/x32 profile and libpng should detect using its configure test script. #

Read the configure output, please. checking for zlibVersion in -lz... no checking for z_zlibVersion in -lz... no configure: error: zlib not installed !!! Please attach the following file when seeking support: !!! /var/tmp/portage/media-libs/libpng-1.6.3-r1/work/libpng-1.6.3-x32/config.log
# q list -Iv zlib sys-libs/zlib-1.2.8-r1 As I said, at "Actual results": configure passes the x64 phase successfully, properly detecting zlib as installed, but fails at the x32 configure phase, with "configure: error: zlib not installed"

It is my fault: I changed the system profile to x32 on an already installed system instead of using the stage3-x32 tarball. As a workaround, one can temporarily set ABI_X86=64 on an x32 profile and get a mixed system first, then, after both libraries (x32 and 64) are in place, recreate the /usr/lib symlink to point to /usr/libx32, remove the custom ABI_X86 setting and emerge -e @world. I'm not sure it'll work, maybe more steps are needed, but it's a start. I won't update this report with my results - one should start with a stage3-x32 tarball.
