Not surprising, the 48 chainring, 34 rear cog, and Rivendell chainstay length are all on the edge of normal these days. You have run into tolerance stack - too many tolerances going one way and you end up out of overall tolerance - in this case; standard chain length. I bought an extra SS 9 speed Wipperman chain just to rob links out of for my various Rivendells. I even commit the sin of using my pin tool to join the extra links by pressing the pin so I have only one quick link.
