The system library openssl required by crate openssl-sys was not found.
The file openssl.pc needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
The PKG_CONFIG_PATH environment variable is not set.

HINT: if you have installed the library, try setting PKG_CONFIG_PATH to the directory containing openssl.pc.

Could not find directory of OpenSSL installation, and this -sys crate cannot
proceed without this knowledge. If OpenSSL is installed and this crate had
trouble finding it, you can set the OPENSSL_DIR environment variable for the
compilation process.

Make sure you also have the development packages of openssl installed.
For example, libssl-dev on Ubuntu or openssl-devel on Fedora.

If you're in a situation where you think the directory should be found
automatically, please open a bug at https://github.com/sfackler/rust-openssl
and include information about your system as well as this message.

Thanks for the report! After investigating, this error results from trying to compile a UDF dependency that requires openssl, which is not installed by default in the Arroyo image. The easiest workaround is to build a custom image that has the extra dependencies installed, for example with this Dockerfile:

FROM ghcr.io/arroyosystems/arroyo:latest

RUN apt-get update && \
    apt-get install -y libssl-dev
