Compilation Fails When Configuring without Normalization or JSON Output

[wrharding]

I have been attempting to compile Sagan on an Alpine Linux container to realize container disk size improvements over Debian. However, I have run into an issue, outlined at wrharding/sagan-docker#1

My configure statement is like so:
./configure --disable-lognorm --disable-libfastjson

When attempting to run make in the outlined compilation steps, I run into the below error:

/sagan # make

I've observed the same issue on an Ubuntu 20.04 Desktop environment:
