this should note the ebuild is responsible for depending on the right vcs
packages. e.g. if you use git, then you need to depend on git.

can't we automate some of the common hosts ? if it says github, we know it's
going to be using at least git.

use `eumask_push` instead
on a related note, i don't think we should encourage the implicit -n operator.
it adds no overhead and really no code maintenance to specify it. conversely,
i'm not sure it can be considered common usage. and even if it is, i still
don't see a good reason to not just use the explicit -n as it's clear to the
reader what it's doing.

the inner die is redundant

prefer -z && myself
[[ -z ${EGO_PN} ]] && die ...

what if GOPATH isn't set ? should this always be appending a colon ?

needs braces around ${EGO_PN}, and shouldn't this be calling `die` ?
would also be useful to show the command you're running:
set -- go get -d -t -u -v -x "${EGO_PN}"
echo "$@"
"$@" || die
