Source code only?

[adamgit]

Previously I found a direct download for Mac, reporting as version 1.5

This fails badly on 9/10 prints with Replicator2, so I was hoping to try the 2.0 version here from github - but on downloading, it appears to only have the raw source code.

Is there anywhere I can download GPX itself?

The sources are GPX itself. What you want is a compiled binary. Compiled binaries are generally not distributed via source repositories such as github (although they could be). With this source repository -- github -- you are expected to compile the sources yourself. For your Mac you will need to download from Apple the XCode developer's toolkit and install it. It is quite large -- couple of gigabytes -- but it is free. You then would go to the directory where you have the gpx sources and enter from a terminal window the command "make" followed by pressing the return key. That will then build the binary for you, "gpx". That binary will, IIRC, be in the same directory where you have the sources. (That is, it won't be placed in some other folder.) You can then run the binary or move it wherever you wish.
