>Description:
As mentioned in the Perl 5.10.1 release notes (perl5101delta(1)) and the 5.14.0 release notes (perl5140delta(1)) Switch.pm was deprecated and removed from the core perl distribution. www/webkit-gtk2 ships with a build script requiring Switch.pm, so we need lang/p5-Switch when building with perl 5.14.0.

This also happens on chromium (see PR 157237) and could happen on other ports.
>How-To-Repeat:
Upgrade to perl 5.14 and try to build webkit-gtk2
>Fix:
Add the following lines to Makefile

.if ${PERL_LEVEL} >= 501400
BUILD_DEPENDS+=	p5-Switch>=0:${PORTSDIR}/lang/p5-Switch
.endif
