Not at all.  Pkg is all about run-time dependencies and knows nothing at
all about what it takes to build anything.  That's what the ports tree
is all about.  As far as pkg is concerned, it doesn't matter how these
go ports are compiled and how the results are divided into packages.  If
it makes sense to build a go program including whatever other go
packages it depends on as one blob and then package up the results all
together, then pkg is cool with that.

The only concern is when the same dependency occurs for two different go
programs (which is probably a good indication that dependency should be
a separate pkg of its own.)  So long as you don't generate conflicts by
trying to install a file of the same name from more than one package,
bundling all the dependencies in with the parent should work.

Not saying that's a particularly good idea, or that installing
essentially the same stuff distributed in multiple places around the
filesystem is a particularly elegant concept -- clearly it isn't, but if
it's a choice between 'elegant' or 'working' then working wins every time.

The ports requirements are a different thing however.  Yes, you will
need to work out how to download all the distfiles for your go program
as a separate step during the 'fetch' phase.  All of those disfiles will
need to be checksummed and matched against the recorded distinfo in the
port.  That's a big deal security-wise.  Note that there is a very
little used 'FETCH_DEPENDS' type of dependency where you can get the
ports to install whatever else you need to manage the downloading part.

	Cheers,
