Answer 1

If you are uncomfortable copying libraries into your system directory, you can use the DYLD_LIBRARY_PATH environment variable to force the OS to search Postgres's library directory for libssl. E.g.:

$ DYLD_LIBRARY_PATH=/Library/PostgreSQL/9.4/lib pip install psycopg2

(documented under the dyld man page).
