What are those requirements that constitute standard FreeBSD system
capable of building ports?

There are more examples
- openssl: WITH_OPENSSL_PORT
- pkg_install: .if exists(...)
- fetch: .if exists(...)
- texinfo: by relying on PATH
And rather than resurrecting shells/tcsh one can also also try
BUILD_DEPENDS +=3D ${CSH}:${PORTSDIR}/shells/44bsd-csh
.if exists(/bin/csh)
CSH ?=3D /bin/csh
.else
CSH ?=3D ${LOCALBASE}/bin/44bsd-csh
.endif
But some ports may assume csh is tcsh like sh is bash on linux.
