To install pgfplots for OSX Yosemite?

Old discussion about this topic for OSX Lion here. However, I think there is no good answer to this topic, since pgfplots is not already installed so not only a .sty file problem, like Alan writes there.

I am trying to run this script here but get the error about the missing pgfplots, after the generation of the Liste.dat:

I run ls /usr/local/texlive/2014/texmf-dist/scripts/pgfplots/ and get

matlab2pgfplots.m   pgf2pdf.sh  matlab2pgfplots.sh  pgfplots.py. 

This suggests me that have the command but the error is internal in pgfplots.

I reinstall the system and run the command sudo tlmgr install --reinstall pgfplots but I get the some error message as above.

How can you install pgfplots in OSX Yosemite?
