lang/go and libc.so.6

Port lang/go installs properly, and issuing the command go run hello.go produces typical "Hello, world!" from the console. However, I have yet to try to actually compile anything even of medium size and I can't even remember the name of the Go compiler (6g or something like that on amd64?). Anyways, when I built it using Portmaster gave the following message:
portmaster lang/go
Code:

/lib/libc.so.7
/compat/linux/lib/libc.so.6
So I added to /etc/libmap.conf
Code:
libc.so.6            libc.so.7
Is this what I should have done?

I have lang/gcc46, lang/gcc47, lang/gcc48. lang/gcc49, lang/clang33 and I think I have another version of Clang installed as well. None of them install a version of lib.c.so.# libc.so.#.

Any advice??? Should I recompile? Should I lipmap to the Linux libc? I mean, maybe that's what it's looking for but I don't think the Linuxulator is required for this port.

Which version of FreeBSD? The libc.so.6 is from FreeBSD 6 as far as I can see from compatibility ports. Install misc/compat6x and see if it works that way. It's really odd though that the port requires such an ancient version of libc.so.

Even weirder, notice
Code:
GOARCH=amd64
yet at the bottom it mentions FreeBSD-386-exec or something of that nature? I installed misc/compat6x and it didn't look like it installed libc.so.6 but I'll check pkg-plist and even if not I'll try to rebuild again anyways. It appears to be working but that message isn't giving me much confidence.

The compat port installs it as /usr/local/lib/compat/libc.so.6. That is probably not going to be used for building new ports. That's even weirder if the old library is needed at build time when there's an up to date library already in the system. I would contact the port maintainer about the issue.

Yep that's the only option. It's still working, installing etc, but the old pkg message is gone (about setting environment variables) and everything so far seems fine. I just get that weird error during the install, not the build.

It looks like it's using some pre-built executable to bootstrap the build process. Probably very much like you need java to be able to build java (this requires FREEBSD_COMPAT7). And I'm guessing the pre-compiled bootstrap was built for FreeBSD 6 hence the need for the FreeBSD 6 libc. But I would have expected the port to depend on misc/compat6x.

I know I'm bumping up an old thread, but I'm still using FreeBSD 10.3-RELEASE-p11 and when installing the latest version of go (1.9.2 at the time of writing this), I still continue to get this error. I'm well aware that this version of FreeBSD is unsupported. Nevertheless, after installation, go works perfectly, the error only occurs during install (of both go 1.4, required to compile 1.9.2, as well as when finally installing go 1.9.2).

Installing go-1.9.3 on a brand new instance of 11.1-RELEASE-p4, and receive the same error yet. Looks like the culprit is in
src/debug/elf/symbols_test.go of both go-1.9.3 and 1.4.

Code:
symbols_test.go:                        Name:    "puts@@GLIBC_2.2.5",
symbols_test.go:                        Name:    "__libc_start_main@@GLIBC_2.2.5",
GLIBC_2.2.5--released January, 2002--provides libc.so.6. And apparently, GLIBC_X.Y.Z still provides libc.so.6. Read more under "Linux libc" on the libc(7) manpage from our Linux colleagues: http://man7.org/linux/man-pages/man7/libc.7.html

However, what remains unknown to me is if this could cause production or security issues.
