Hi to all,

I'm trying to port google mtail but I don't understand how go (and go ports
work),
I have experience only in Perl ports in OpenBSD, I have the following

Makefile:
COMMENT =       extract monitoring data from logs for collection in
timeseries databases

MODGO_MODNAME = github.com/google/mtail
#MODGO_VERSION =        latest
MODGO_VERSION = v3.0.0-rc9+incompatible # generated by make
modgo-gen-modules

DISTNAME =      mtail-${MODGO_VERSION}

CATEGORIES =    sysutils

HOMEPAGE =      https://google.github.io/mtail

MAINTAINER =    Abel Abraham Camarillo Ojeda <acamari@verlet.org>

# Apache-2.0
PERMIT_PACKAGE =        Yes

#WANTLIB += ${COMPILER_LIBCXX} pthread z c m tag

MODULES =               lang/go

#.include "modules.inc"
.include <bsd.port.mk>

But "make build" fails with:

merced$ make build

make modgo-gen-modules returns only:
$ make modgo-gen-modules
MODGO_VERSION = v3.0.0-rc9+incompatible # add this to Makefile, not
modules.inc
$

The +incompatible might be the culprit...

ideas into how to progress?

Thanks
