Well I had to package most of the first-level deps myself, and rebuilt the 
next-level deps in EPEL to rawhide's level, though I'm sure I missed some bits 
and didn't have the time yet to verify all the deps are at the same level.

I tested once or twice by wiping everything but the spec files, spectooling 
sources, and rebuilding everything from scratch. So the specs should be 
sufficient by themselves to reproduce.

No problem, here they are. The aim of the pile of packages is to build the 
prometheus snmp exporter. It works flawlessly in EPEL/7 but fails in rawhide 
with

./main.go:120:14: cannot use kingpin.CommandLine (type *kingpin.Application) as 
type *flag.FlagSet in argument to "github.com/prometheus/common/log".AddFlags

WARNING 1 

The specs depend on custom macros because I was sick to death of the 
boilerplate in Fedora Go spec files (too error-prone for my fat fingers). That 
makes the specs easier to read but not to build right now. I hoped to play a 
little more with the macros before submitting them to public review. So happy 
review, I hope you like the result:).

You can not build the packages if the srpm macros are not available when the 
build system first reads the spec file. For my needs I just add the package 
name to the 
  config_opts['chroot_setup_cmd'] = 'install @buildsys-build'
mock line, I didn't check how to do it in koji yet.

The right way to do this would be to merge the macros in the golang package, 
make it export an srpm-macros subpackage, and add the subpackage to the 
buildsys-build group. That would also gift you the maintainership of the result 
in my so cunning plan, sorry about the surprise, I did expect to introduce you 
the idea some other way :).

WARNING 2

There is a dependency loop in the set, golang-github-sirupsen-logrus needs 
building with bootstrap the first time (I hope I got the Fedora bootstraping 
conventions right)

All tips, remarks and technical criticism are welcome.

WARNING 3

There are some common_description remnants in the specs. They serve no 
particular purpose. They are leftovers from the time I created unit test 
subpackages, before I decided I wanted to run the tests in check but not to 
ship the unit test files once the build is done.

Regards,

PS
It would be nice if the golang packages were published in a centos or epel 
repo. Right now you have to fish them directly from the centos koji instance. 
And yes I also have access to paid-for RHEL7 packages.
