Hi!
You should have just send the relevant part of the log which is:

This basically says that you have duplicate definitions of the statfs in your
system headers i.e. they are both in sys/statfs.h and sys/vfs.h.

And usually the vfs.h just includes statfs.h, so it really looks like your
system, more specifically libc headers are horribly broken.
