Thanks a lot for the trick, I was able to finish compiling it, but going 
another route (i.e. unbundling htslib).

I've abandoned running the tests though, I'm hitting a module not found 
error. pytest doesn't manage to load the just built module, probably an 
issue with the paths.

I'm attaching the new version for reference.

Cheers,
Alexis
