You can read the newsletter on the web, if you prefer.

A good mixture of all sorts of topics this week,
and my favourite of them is Lee Johnson's All Software is Legacy.
Oh, and if you appreciate Tony Cook's work on Perl 5,
why not add a supportive comment to the post about
his grant request.

Fixing prereqs in dist.ini automatically
https://perlancar.wordpress.com/2016/03/04/fixing-prereqs-in-dist-ini-automatically/
Perlancar's lint-prereqs ( https://metacpan.org/pod/lint-prereqs ) script
can be used to check whether your distribution has (the right versions
of) all the right prereqs, and if you're using Dist::Zilla (
https://metacpan.org/pod/Dist::Zilla ) it can even fix up your
dist.ini
. I've never had any problems using
[AutoPrereqs]
, but I know that not everyone does.

MacPorts openssl versus Perl

Tom found that a failure with LWP::Protocol::https (
https://metacpan.org/pod/LWP::Protocol::https ) was due to an upgrade
from 1.0.2f to 1.0.2g of OpenSSL. He shows how you can downgrade a
MacPort. You should be aware of the security issues (
https://openssl.org/news/secadv/20160301.txt ) announced this week (the
most widely reported being the DROWN attack ( https://drownattack.com )),
which affected older versions of OpenSSL ( https://openssl.org ).

Sinan noticed that a certain distribution fails to install on Cygwin, and
tracked it down to this: if a tar file has foo
and foo.exe
, then when you extract from the
tar file you'll get foo
but not foo.exe
. See
here ( https://cygwin.com/ml/cygwin/2009-08/msg00293.html ) for example
