Web system development uses user Perl, but IO::Socket::SSL must be installed to support HTTP communication.
IO::Socket::SSL depends on Net::SSLeay, while Net::SSLeay depends on OpenSSL headers and libraries.
For the location of the installed OpenSSL header files and libraries, see Header file read path and Library loading path.
