 Hi,

 It appears from the gnuplot readme:


 {{{
    IMPORTANT NOTE ON PDF SUPPORT
    ===========================================

    Direct PDF support in gnuplot is provided by an external library.
    Two options are currently possible.  It is possible to have both
    PDF terminal drivers in the same gnuplot executable.

    The newer "pdfcairo" terminal uses the pango and cairo libraries.
    This driver will be built if the configure script detects suitable
    versions of cairo and pango on your machine.
 }}}

 that, if pango and cairo are available, pdflib is not strictly needed.
 I therefore suggest the following change to the gnuplot Portfile:


 {{{
 @@ -103,6 +103,7 @@

  variant pangocairo description "Enable cairo-based terminals" {
      depends_lib-append      path:lib/pkgconfig/pango.pc:pango
 +    depends_lib-delete      port:pdflib
      configure.args-delete   --without-cairo
  }
 }}}

 this is particularly important to me as pdflib has a restrictive
 license, while pango and cairo are free software.

 Alternatively, as both options are allowed at the same time, one could
 ad a new separate variant 'pdflib' but I don't think it is very useful
 to have two pdf terminals available ...



 thanks,



 c.
