I don't know much about buildlink, so I'm not sure how I would go about
that. One thing I've found is that if I include '-ldl' in $CFLAGS,
$CPPFLAGS or $LDFLAGS, it gets ignored by mMosaic's Makefile.

The only way to get '-ldl' into cc's command line was to pass it via
custom variable 'syslibs', that mMosaic's Makefile will read. Note that
pkgsrc's Makefile is already using this nonstandard mechanism with the
'sysconfigflags=' assignment.
