  That would have been me.  If a package cannot be built unless it is
already installed, that package is broken, as it breaks a number of
pkgsrc's key assumptions (like reproduceable builds).  And no amount
of arguing is going to change that.

  IIRC, SITES.<filename-of-distfile> overrides MASTER_SITES for a
particular file.  That failing, you can set MASTER_SITES to point both
to the original download site and to the packages directory.  That
will search both files in both places, which is neither elegant nor
efficient, but should work.
