>Description:
The FreeBSD port devel/p5-ExtUtils-CBuilder is missing a dependency upon devel/p5-IPC-Run and succeeds with install but fails at run-time.

There's a complaint in the forums at:
  http://forums.freebsd.org/showthread.php?t=20571

Verified on my system:
% perl -e 'use ExtUtils::CBuilder'
Can't locate IPC/Cmd.pm in @INC (@INC contains: [...]

This affected my ability to install converters/p5-Encode-Punycode as it led to "configure"-time complaints:

Warning: ExtUtils::CBuilder not installed or no compiler detected
Proceeding with configuration, but compilation may fail during Build

Marking serious as it is leading to port build failures with diagnostics which hide a dependency.
>How-To-Repeat:
Attempt to install converters/p5-Encode-Punycode on a clean system.
>Fix:
ports/devel/p5-ExtUtils-CBuilder/Makefile needs to gain something like:
  RUN_DEPENDS=  p5-IPC-Run>=0:${PORTSDIR}/devel/p5-IPC-Run

(warning: untested, I just installed the module manually to get things working)
