The src.conf manpage is not in error.  The intent is that src.conf
applies only to the building of the freebsd world and kernel, that is,
the source that's usually located under /usr/src.  If settings from
src.conf are leaking into other builds, the error is in the makefiles,
not in the manpage.  

Unambiguous evidence of this can be found in the email announcing the
new src.conf file and why it was created:


I'm not an expert with the build system, and that goes double for ports,
so I can't say exact how or why it's broken, or when the breakage
happened (or even if it's been broken from the very beginning), but I
think that announcement email makes it clear the bug isn't the
