Bug#950633: morris: FTBFS with boost1.71 deprecated signals library is removed

[Dimitri John Ledkov]

Package: morris
Version: 0.2-5
Severity: serious
Tags: ftbfs

Dear Maintainer,

boost1.71 has removed the deprecated signals library, thus morris
cannot be build against the upcoming boost ABI.

Given how old the libraries it uses are, maybe we should even remove
morris from the archive, as it is no longer practical to keep it in.

Regards,

Dimitri.
