• Change that to ntc.storage.pgaskin.net. I just haven't gotten around to updating it yet.
• You'll also need to modify niluje/x-compile.sh to pin https://github.com/zlib-ng/zlib-ng.git to a version at around the time of the last commit; I overlooked that one when pinning the versions.

I modified the line to read as

until git clone -b 2.0.2 https://github.com/zlib-ng/zlib-ng.git ; do

But it still runs the old command when I run docker build ., seems the x-compile.sh is cached somewhere. Any idea how to clear it?
