--------------------------------------------+-------------------------------
 I worked over the portfile to get rid of two quiet large dependencies.

 - deleted dependency: xorg-libX11[[BR]]
 Not needed. The pari website only lists an optional colour-capable xterm.
 The OS X Terminal suffices.

 - deleted build dependency: texlive[[BR]]
 Only needed to build the pdf documentation, but quiet large.

 - new variant: docpdf[[BR]]
 For those who wish to build the pdf documentation. Depends on texlive. My
 first idea to use the natively installed TexShop didn't work out, but
 would be favorable. I think the (untypical) exclusion of the documentation
 presents the next best solution since the pdfs are also available on the
 pari website.
