moshが起動しなくなって困る

Debian sid amd64環境でmoshが動かなくなった．

$ mosh
IO.c: loadable library and perl binaries are mismatched (got handshake key 0xed00080, needed 0xeb00080)

Mosh: the mobile shell

mosh-clientは動くけど ~/.ssh/config を見てくれないので面倒

$ mosh-client
mosh-client (mosh 1.3.2) [build mosh 1.3.2]

Usage: mosh-client [-# 'ARGS'] IP PORT
       mosh-client -c

mosh は perl script

$ file /bin/mosh
/bin/mosh: Perl script text executable
$ grep -v ^# /bin/mosh | head


use 5.8.8;

use warnings;
use strict;
use Getopt::Long;
use IO::Socket;
use Text::ParseWords;
use Socket qw(IPPROTO_TCP);

mosh-client はelf

$ file /bin/mosh-client
/bin/mosh-client: ELF 64-bit LSB pie executable, x86-64, version 1 (GNU/Linux), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, BuildID[sha1]=9145424edb62c61b0081efeaa68ea20a25a73e5f, for GNU/Linux 3.2.0, stripped

sidだしPerlのアップデートもあったのでそのせいかなと思っていたけどしばらく経っても直らない．

cpanやcpanmも動かない．cpanは ~/perl5 を見ている．
最近Debian sidのPerlのバージョンが上がったのに ~/perl5 を更新していないので不整合となっていたよう．
一旦 ~/perl5 を退避して動作するように．
ディストリビューションアップデート時などにも嵌りそう．

$ cpanm --list
