Do you have the postgresql source files available?

In case anyone else is encountering this error like me, I had a dockerfile based on postgres:16-alpine, that installed clang15 and llvm15.
Like so:

FROM postgres:16-alpine

ENV PG_PARTMAN_VERSION v5.0.1

RUN apk update

RUN apk add --no-cache \
        ca-certificates \
        openssl \
        tar \
        autoconf \
        automake \
        g++ \
        clang15 \
        llvm15 \
        libtool \
        libxml2-dev \
        make \
        perl

# Install pg_partman
RUN wget -O pg_partman.tar.gz "https://github.com/pgpartman/pg_partman/archive/$PG_PARTMAN_VERSION.tar.gz" \
    # Create a folder to put the src files in
    && mkdir -p /usr/src/pg_partman \
    # Extract the src files
    && tar \
        --extract \
        --file pg_partman.tar.gz \
        --directory /usr/src/pg_partman \
        --strip-components 1 \
    # Delete src file tar
    && rm pg_partman.tar.gz \
    # Move to src file folder
    && cd /usr/src/pg_partman \
    # Build the extension
    && make \
    # Install the extension
    && make install \
    # Delete the src files for pg_partman
    && rm -rf /usr/src/pg_partman

It suddenly stopped working, and the issue was that the maintainer of postgres:alpine bumped the clang and llvm versions to 19, which broke my installation setup. I had to bump the versions in my dockerfile as well.
