I've upgraded our BioBrew roll from 4.1.1 to 4.1.2 following the instructions from Glen Otero. When rebuilding an i386 node the installer errors on byacc. It says it cannot find byacc-1.9.28. The 4.1.2 roll has byacc-1.9.29. I still have the 4.1.1 roll, should I delete that directory and rebuild with rocks-dist to fix this? -- Jeremy
