There are 62 libboost-dev packages!

But luckily I got it compiled by downgrading libssl-dev (version 1.1) to libssl1.0-dev. So it is probably this API change in OpenSSL. It broke a lot of software. After starting it did synchronize VERY quickly, but then it stopped at 1 hour behind. Processed 121171 blocks. At the moment it has 4 peers, three with 0.9.3 and one with 0.9.2. I started a verifychain. Maybe there is an issue.

Thanks.

PS: Or maybe the problem was the chain itself? Now I am up to date with 121172 blocks.
