A quick 'n dirty hack in the FETCHCOMMAND should suffice. Something along the
lines of (pseudocode):

FETCHCOMMAND="if exists \${DISTDIR}/`basename \${URL}.lck`; then skip; else \
              touch \${DISTDIR}/`basename \${URL}.lck`; \
              /usr/bin/wget ...; \
              rm \${DISTDIR}/`basename \${URL}.lck`; fi"

This of course as a temporary solution ;)
