The general idea looks good, but I would expect FETCH_USING=manual to
mean "the user will manualy place distfiles in DISTDIR; pkgsrc should
not automatically fetch distfiles in any way at all".  I suggest using
FETCH_USING=custom to mean "pkgsrc should fetch distfiles using the
custom command and arguments specified in FETCH_CMD, FETCH_BEFORE_ARGS,

I think that's too restrictive, because it makes it difficult for users
to specify FETCH_CMD in mk.conf but temporarily override FETCH_USING
from the command line.  Perhaps make it a warning (not an error) if
FETCH_CMD and friends are set but FETCH_CMD != "custom".

No, make it an error if FETCH_USING=foo but foo is not installed.
The user can use .if exists(...) conditionals in mk.conf to set
FETCH_USING=wget or FETCH_USING=ftp depending on whether or not wget is
