thanks for your help offering! very kind.

I've already solved the problem - not with the suggested process, but via
copying missing libs and files from and identical intact source. After that, I
ran make buildword/buildkernel and was able to successfully install the new

As I stated before: I already had a complete compiled world and kernel existing
in their proper, intact folders (usr/src and usr/obj). There was no need to
compile a whole world.
Intending to "make installworld" failed, this is the real problem, because the
ISO/memstick images provided lack obviously in the required infrastructure and
so these images are worthless for sophisticated rescue operations - or even
such a simple ask as described initially in my posting.

I created images on CURRENT of my own - they all lack in the ability of having
the necessary tools aboard. So I consider every image useless for rescue
operations except, maybe, the DVD image - but this one is not provided anymore.
For what reason? Time? Accepted. Space/disk usage? Well, welcome back in the
stoneage of computer technology ... 

I remember faintly that there was a small discussion on the @CURRENT list, but
I didn't realize that the result would be the extraction of the compiler.

Just for the record: most servers delivered to us do not have CD/DVD drives
anymore - they are outdated and considered an extra these days. Purchasing 1 GB
USB thumbdrives is getting even harder, smallest size my employer provides now
is 2 GB. And most optical drives are DVD. From my point of view - and this is a
personal view - the "standard" is > 1GB so there is no need to break down by
force the FreeBSD image (if size is the reason) down to < 800 MB or < 1 GB. I'd
consider having < 2GB the line of standards (2 GB USB mem drive).
And for those, with need of very small images, smaller images could be provided
as the extra.

Thank you very much,
