There are two errors, see below:

The above is a warning, it is a configuration problem with one or more 
layer.conf file within a layer.  But it's a warning, the build will continue.

The above is an error.  Your shell environment's "PATH" is broken.  You have 
either '' (blank) or '.' within your path.

Run the following in your shell: echo "${PATH}"

If you see something like:

/usr/bin:/bin:~/bin:.

It's the '.' that is the problem.  Rewrite your path by removing the '.' item.. 
(similarly if it contains '::' or ends with ':' that is the blank problem)
