Usage: PGPLOT_install [options] 
Options: 
  --prefix=PREFIX   base directory for installation [$prefix]
  --system=SYSTEM   operating system type for PGPLOT drivers [$system]
                    typical values would be   linux irix sun4 

  --with-png  / --no-png   add/remove PNG driver
  --with-gif  / --no-gif   add/remove GIF driver

  --with-64bit      use for 64bit linux machines (links to X libs in /usr/X11R6/lib64)

  --with-fortran    explicitly set fortran compiler executable
  --with-fflagc     explicitly set fortran compilation flags

  --no-log          do NOT generate PGPLOT_install.log
  --no-clean        do not remove any files created during build
