If your project is a package, usually (IMHO) you should forget about making
builds reproducible.
This is responsibility of the develper that uses your package in his
project.
b) use SemVer 2.0.0 versioning.

For web applications I use the layout proposed by Dave Cheney in db (but
this layout seems to be used by other projects, too).
I use gb build when building, since it is convenient, but I use standard go
tools for everything else, using this script named go+"
#!/bin/sh
# Execute the go tool for the current project.
# The project should have the layout as defined by the gb tool.
GOPATH="$PWD:$PWD/vendor" GOBIN="$PWD/bin" go $@
When importing dependencies I use gb vendor fetch, but for some cases I
just clone the repository inside vendor/src/.
If your project is a package you can import the dependency in a vendor
directory. There are some example in the Go standard library.
However you should be careful, since some packages can not be imported
multiple time (like the SQL drivers).
