Your fix for that and most of the rest is ok, but this is problematic
for those who already have the distfile:

> -SHA256 (netpipes-4.2-export.tar.gz) = bu2JtmGunyrA04NBTKlkq+qKEV+Pug96s3tJtWX/sqg=
> -SIZE (netpipes-4.2-export.tar.gz) = 74977
> +SHA256 (netpipes-4.2-export.tar.gz) = BxKyzVWteAhDhdIV+AN6rTxTsGpv2Mm9qD7COv1ECic=
> +SIZE (netpipes-4.2-export.tar.gz) = 75276

You'll need to rename the distfile with the {} mechanism in DISTFILES
to add something like -1 to the new one.
