What ports require this port?

[Dan Langille]

Over the weekend, a new feature was added to FreshPorts BETA.  A port 
now lists all ports that require it.  This code will eventually move to 
production after it's been running on on the beta site for a while.

Notes:

* The code uses the output of make -V RUN_DEPENDS -V LIB_DEPENDS -V 
BUILD_DEPENDS
* Only the default build is queried
* This is not recursive.

For example, at

  http://beta.freshports.org/graphics/png/

You will find:

Required by:
for Build
graphics/iiview graphics/optar graphics/tumbler

for Libraries
astro/astrometry astro/celestia astro/celestia-gnome [long list snipped]
