 Priority:  Normal                   |   Milestone:  Port Enhancements      
Component:  ports                    |     Version:  1.7.0

-------------------------------------+--------------------------------------
 There are several ports that list `--prefix=${prefix}` in the
 `configure.args`. It's not necessary to do that because MacPorts already
 puts `--prefix=${prefix}` in the `configure.pre_args`. The attached patch
 removes `--prefix=${prefix}` from the `configure.args` where it's
 unnecessary. These ports are affected:

  * arabica
  * arts
  * avr-libc
  * axel
  * bigloo
  * blackbox
  * blt
  * bochs
  * clisp
  * dcfldd
  * ffmpeg
  * fnlib
  * fuzz
  * gmime
  * grads
  * httperf
  * mcabber
  * ncview
  * netclasses-framework
  * nspr
  * pidgin-encryption
  * py-4suite-xml
  * rep-gtk
  * rrdtool
  * sawfish
  * scotty
  * swi-prolog-devel
  * sympa
  * szip
  * taskjuggler
  * tivodecode
  * tktable
  * wormux
  * yaws

 The maintainers of all affected ports are Cc'd. If you have no objection I
 will commit this in a few days. If you do not want me to change your port,
 please explain here.
