the command 'scons --ssl=SSL' returns:

/usr/bin/ld: util/net/sock.o: undefined reference to symbol 'ERR_load_crypto_strings'
/usr/bin/ld: note: 'ERR_load_crypto_strings' is defined in DSO /lib/libcrypto.so.10 so try adding it to the linker command line
/lib/libcrypto.so.10: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

We missed one linking lib on SConstruct.

I've done a simple fix, will comment later.
