Do you mean Grand Central Dispatch? As described here: http://wiki.freebsd.org/GCD It's not generally used in the ports because it isn't supported in any released version yet -- the up and coming 8.1-RELEASE will be the first to have it. It's also still considered experimental. Additionally, the userland bits need to be compiled with llvm/clang to support a major chunk of useful functionality (blocks). If you want to try it out, the userland parts are available as devel/libdispatch, and you'll need 8-STABLE as of last November, or any more recent 8.x or 9.x. Options for enabling GCD support in ports that are capable of it will no doubt appear over time. Port maintainers will almost certainly be glad to receive patches to do that.
