The only variables currently being allowed in an URL is ${name} and that
is due to special handling in proc portfetch::mirror_sites in

Furthermore, ${distfiles} is meant to be list of all files to be
downloaded. If a port has multiple files to be downloaded that URL would
be invalid.

Notwithstanding possible changes to base to accommodate such an URL in a
better way, I would propose to use the following:

  set portfetch::mirror_sites::sites(php) {

  distname        php-${version}
  use_bzip2       yes
  master_sites    php:[suffix ${distname}]/from/this/mirror?dummy=

If multiple files are required for a port, these could still be pinned
to a specific master_site using tags. My solution is kind of a hack, as
it abuses the subdir component, but I can't think of anything better
with the current base.
