Comment:

 Hhm... it still fails on 10.6 with the same error. Of course there is no
 strict requirement to support these old systems, but perhaps this can be
 fixed. The build uses `pkgconfig` to get the required include directories
 for `liblz4` and such, and will not use `-O3` if `liblz4` is found. I
 verified that this all works correctly on 10.15 when I updated the port,
 but it appears not to work properly on 10.6.

 I don't have a system with such an old OS, but if someone wants to try and
 help out please try to install the port `sudo port install py310-lz4`,
 which presumably will fail. Then please post the output of:
 {{{
 python3.10 -c "import pkgconfig; print(pkgconfig.exists('liblz4')) ;
 print(pkgconfig.libs('liblz4')) ; print(pkgconfig.cflags('liblz4'))"
 }}}
