@INC and 'use lib' won't work because you're working with an external ( non-perl ) command. @INC is a library-location directory. it's where you would find perl functions/modules.

the assignment to $ENV{PATH} looks like it would work . . .

why not simply hard-code the openssl program: 

$openssl = '/usr/local/openssl/bin/openssl';
