bitcoin: error: explicit instantiation of ... but no definition available

[scott@…]

Seems to be in "boost" (main.log attached).

Probably an incompatibility with the latest boost, like we've seen in lots of other ports. You could try downgrading boost or upgrading bitcoin.

I think this ticket might be changed to 'fixed' or 'closed', see #37353.

finance/bitcoin updated to 0.8.0 in r103500 which seems to build fine.
