Crypt-SSLeay on a macbook

I'm trying to install Crypt-SSLeay on a macbook and it failed. I manually downloaded Crypt-SSLeay from cpan and issued: perl Makefile.pl The error is openssl-version.c:2:10: fatal error: 'openssl/opensslv.h' file not found #include ^ 1 error generated. Failed to build and link a simple executable using OpenSSL The file exists and it's located at: /usr/local/opt/openssl/include/openssl How do I go about fixing this, thanks.
