This was built back when Wine wasn't as good and you needed workarounds and hacks for BFME to work on Linux. We have upstreamed most required fixes, and on Linux, you can now just download BFME via https://bfmeladder.com (or any other community hosted service) and it should Just Work.
For other open source BFME projects, see https://github.com/Open-BFME
