I'm on Macbook M2, running macOS 15.4.1 with the latest FPC installed via homebrew.
Seems there's an issue with fppkg
$ fppkg list
Warning: Could not initialize OpenSSL library
Name Installed Available
BTW, I already had OpenSSL3 installed also via Homebrew, and also had this in my .zshrc
export PATH=$PATH:$(brew --prefix openssl@3)/bin
export DYLD_LIBRARY_PATH=$(brew --prefix openssl@3)/lib:$DYLD_LIBRARY_PATH
