 Attempting to upgrade the ImageMagick package, ports detect the p7zip
 extract dependency. It then attempts to upgrade p7zip although I already
 have it installed:

 {{{
 # port install ImageMagick
 --->  Building p7zip
 ^C
 }}}

 Some informations:

 {{{
 # port deps ImageMagick
 Full Name: ImageMagick @6.7.0-0_0+q16
 Extract Dependencies: p7zip
 ...

 # port installed p7zip
 The following ports are currently installed:
   p7zip @9.13_1 (active)
 #  port info p7zip
 p7zip @9.20.1 (archivers)
 ...
 }}}


 The extraction dependency should not rely on the version and it should not
 trigger an upgrade of the extracting package.
