Is it a bug in ledger port file that ledger does not detect upgrade of
boost? Should I better report it in trac? Or is there a different way of
going through boost upgrade?
I encountered this yesterday myself, with exactly the same results that you
describe. I filed a ticket on this at
<https://trac.macports.org/ticket/58911>, and it was just marked as
"fixed." I haven't actually looked yet myself; perhaps there's a new
ledger package that fixes the issue?
Its marked fixed simply because ledger was rev-bumped to trigger a
rebuild of the binaries against the new boost. There is no 'bug' here,
just a rebuild that is required.
