"policyd-weight is a policy daemon for the Postfix MTA". Since it's written in Perl, it works just fine on amd64. I've sucessfully setup the 0.1.14.5 ebuild on a amd64 box yesterday (after adding ~amd64 of course), and it's up and running perfectly. So should every other release.
Confirmed. Works fine on AMD64.
