Do you really need Crypt::SSLeay?

Starting with version 6.02 of LWP, https support was unbundled into
LWP::Protocol::https. This module specifies as one of its prerequisites
IO::Socket::SSL which is automatically used by LWP::UserAgent unless
this preference is overridden separately. IO::Socket::SSL is a more
complete implementation, and, crucially, it allows hostname
verification. Crypt::SSLeay does not support this. At this point,
Crypt::SSLeay is maintained to support existing software that already
depends on it.

However, it is possible that your software does not really depend on
Crypt::SSLeay, only on the ability of LWP::UserAgent class to
communicate with sites over SSL/TLS.

If are using version LWP 6.02 or later, and therefore have installed
LWP::Protocol::https and its dependencies, and do not explicitly use
Net::SSL before loading LWP::UserAgent, or override the default socket
class, you are probably using IO::Socket::SSL and do not really need

Before installing Crypt::SSLeay, you may want to try specifying a
dependency on LWP::Protocol::https.
