Hey all,

I've been trying to get Thunderbird to build for a few days now.
Since I'm pretty much out of ideas at this point, I figured I'd ask on here if someone has an idea on what my problem is.

I've attached the output of `emerge --info '=mail-client/thunderbird-52.3.0::gentoo'`, `emerge -pqv '=mail-client/thunderbird-52.3.0::gentoo'`, and the complete build log.

From the error message I can see that it likely has something to do with either libpng or zlib.
I have both of those installed:

$ emerge --info libpng
--- >8 ---
media-libs/libpng-1.6.29::gentoo was built with the following:
USE="apng (-neon) -static-libs" ABI_X86="32 (64) (-x32)" CPU_FLAGS_X86="sse"

$ emerge --info zlib
--- >8 ---
sys-libs/zlib-1.2.11::gentoo was built with the following:
USE="minizip -static-libs" ABI_X86="32 (64) (-x32)"


I noticed that I have zlib-1.2.11 installed, though Thunderbird (or libpng?) is apparently trying to reference a symbol from zlib 1.2.9.
I tried downgrading to zlib 1.2.9, but...

# emerge --ask \=sys-libs/zlib-1.2.9

These are the packages that would be merged, in order:

Calculating dependencies... done!

emerge: there are no ebuilds to satisfy "=sys-libs/zlib-1.2.9".


I'd really appreciate any hints on what I'm doing wrong here. Thanks!
