pkg-config --modversion zlib
1.2.10

found this while trying to upgrade a port that now explicitly requires zlib 1.2.11 and thought I had to update to 12.2 instead of just waiting for 13, but everything I am seeing is suggesting 1.2.11 is in the base of releng12.1 but the pc file is versioned incorrectly. Not sure if maybe there was a reason it was held at 1.2.10, or if it should in fact be 1.2.11

when i edit /usr/libdata/pkgconfig/zlib.pc to reflect version 1.2.11 the port builds and runs fine, but not sure this is correct and will be clobbered on any new patches to releng12.1 during install. releng12.2 no longer has the lib/libz/zlib.pc file which may be the issue, perhaps it uses the sys/contrib/zlib.pc.in file to dynamically produce the pkg-config pc file? else the library source files seem to be identical in the git repo. 12.1 is old in the tooth, but it is still listed as a supported version so I figured I post the potential bug. I didn't check the 11.4 branch.
