brew install openlitespeed does not work

[gik254]

I did brew install openlitespeed (on MacOS 14.6.1) and I got this (after a while):
...
checking for the location of zlib... /Library/Developer/CommandLineTools/SDKs/MacOSX14.sdk/usr
checking for pkg-config... (cached) /opt/homebrew/Library/Homebrew/shims/mac/super/pkg-config
checking for libzip... /opt/homebrew/Library/Homebrew/shims/mac/super/pkg-config: line 12: /opt/homebrew/opt/pkg-config/bin/pkg-config: No such file or directory
/opt/homebrew/Library/Homebrew/shims/mac/super/pkg-config: line 12: exec: /opt/homebrew/opt/pkg-config/bin/pkg-config: cannot execute: No such file or directory
not found
configure: error: Please reinstall the libzip distribution

I did reinstall the libzip, but no change.

BTW, the only pkg-config in /opt is this:

find /opt -iname pkg-config

/opt/homebrew/Library/Homebrew/shims/mac/super/pkg-config
