------------------------------------------+-----------------
 When I try to instal g95 on macOS 10.12.4 Sierra, the build crashes.

 I read the log, I thought that it might be for two reasons: the clang I'm
 using doesn't recognize the character # for comments, or that a folder
 called "lbzip2" it moved from the location where it supposed to be.

 The box below is what shows the terminal while running with on debug mode.
