SuiteCRM 8.1 on FreeBSD: Installer locked

Ok, the only error left is this:

ZLIB Compression Module | error | ZLib support not found: SuiteCRM reaps enormous performance benefits with zlib compression.

I have php80-zlib and php80-zip modules already installed. Any hint?.

Ps. to fix the previous error messages I had to chown o+w and o+x some specific directories and files under public/legacy.
