pgf binary package in Ubuntu Trusty ppc64el

 pgf stands for `portable graphics format'. It is a TeX macro package
 that allows you to create graphics in your TeX documents using a
 special pgfpicture environment and special macros for drawing lines,
 curves, rectangles, and many other kind of graphic objects. Its usage
 closely resembles the pstricks package or the normal picture
 environment of LaTeX.
 .
 Although pgf is less powerful than \pstricks, it has the advantage
 that it can generate both PostScript output and pdf output from the
 same file. The pgf package works together both with dvips and
 pdftex. In particular, packages that rely on pdftex or pdflatex (like
 some packages for creating presentations) can be used together with pgf.
