Install Net::SSLeay on Ubuntu server

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

I am unable to install Net::SSLeay. This is what I try:

To be sure that openSSL and headers are not missing:

$ sudo apt-get update
$ sudo apt-get install libnet-ssleay-perl

Reading package lists... Done
Building dependency tree... Done
Reading state information... Done
libnet-ssleay-perl is already the newest version (1.92-1build2).

$ cpan Net::SSLeay
[download]

This is the last part of the error:

Any idea?

`/usr/bin/ld: cannot find -lz: No such file or directory collect2: error: ld returned 1 exit status` [download] Seems like you need the dev packages for -lz, i.e. something like zlib-devel. `map{substr$_->[0],$_->[1]\|\|0,1}[\\|\|{},3],[[]],[ref qr-1,-,-1],[{}],[sub{}^ARGV,3]`	[reply] [d/l] [select]

You are mixing your OS package manager and your Perl installation. This will mainly lead to tears and a broken OS installation. The installation error you get from `cpan` likely means that `libz` resp. the ~~`libz-devel`~~ `zlib-devel` package is not installed.	[reply] [d/l] [select]

Doing this, solves the issue `sudo apt-get install libnet-ssleay-perl sudo apt-get install libcrypt-ssleay-perl` [download]	[reply] [d/l]
