When trying to install Crypt::SSLeay on Mac OS X I get the following error:
$ sudo perl -MCPAN -e shell

I have installed openssl as per the instructions found here and the output of openssl version -a is:
OpenSSL 1.1.0f 25 May 2017
built on: reproducible build, date unspecified
platform: darwin64-x86_64-cc

ENGINESDIR: "/usr/local/mac-dev-env/openssl-1.1.0f/lib/engines-1.1"
I'm not sure what else I can do, as I have the ssl library required but it doesn't seem to link it?

Answer 1

OPENSSLDIR: "/usr/local/mac-dev-env/openssl-1.1.0f/ssl"
This is not a standard location for openssl. Which explains why it cannot find the necessary files:
Cannot link with any of the requested SSL libraries 'ssl, crypto, ssl32, ssleay32, eay32, libeay32, z'
When looking at the README for Crypt::SSLeay you will find:
If you have OpenSSL headers and libraries in nonstandard locations, you can use
$ perl Makefile.PL --incpath=... --libpath=...
There are further instructions in the README how to set the path when using cpanm etc.
Apart from that, in most cases you don't want to install Crypt::SSLeay but instead Net::SSLeay. Crypt::SSLeay is only supported to keep older versions of LWP working, all newer things (including current versions of LWP) use Net::SSLeay and IO::Socket::SSL on top of Net::SSLeay.

Answer 2

If this is related to installing LWP::Protocol::https , because you wanted to use LWP::UserAgent ... you will be bettor off installing: IO::Socket::SSL instead off aforementioned Crypt::SSLeay

Answer 3

As stated above, in README it's mentioned "--incpath" and "--libpath" to use custom paths to your openssl instalation.
So it should be something like this (Note:check your openssl version, in this example it's 1.1.1d):
$ sudo perl Makefile.PL --incpath="/usr/local/Cellar/openssl#1.1/1.1.1d/include" --libpath="/usr/local/Cellar/openssl#1.1/1.1.1d/lib"
I struggled to understand what path should be used on those parameters. Those worked though.
