You run into a similar problem if you have distfiles in /cdrom/ports/distfiles
and do `make FETCH_CMD=wget FETCH_SYMLINK_DISTFILES=yes fetch'. The problem gets
worse if you do `make FETCH_CMD=curl fetch'. Either:

- only `fetch' is supported, and you can use FETCH_CMD only to specify a different
  path to the binary

or

- we have a reason to support other file transfer utilities (e.g. they support
  distributed downloading or special firewall protocols) and have to fix this.

So, what do you think?
