I have no clue what pgfplotsbinary.data.code.tex does, but simply
bypassing that works for the simple example above.

Simply create an empty file with the name pgfplotsbinary.data.code.tex in
your current directory and compile your example.

Note that if your code uses any of the features which are provided by this
file (and I am not sure what they are), then it will fail. But at least
this "fix" works for the simple example above.
