Just a note and word of warning for people updating packages with
arch specific distfiles like lang/sml-nj.  make makesum only inserts
the checksums for the files of your arch into distinfo.  Running
make makesum on a different machine may replace those file checksums
with a different set of files and checksums.

I manually merged the i386 and sparc boot file sums into distinfo
for this package, but if this is going to be updated often, or lots
of other packages do this, it may be desirable to add a makeallsums
target that will create the union of all possible makesum results.
