sslsplit on MacOS doesn't compile

[Kurt Schreiner <ks%ub.uni-mainz.de@localhost>]

Hi,

trying to build sslsplit on MacOS (Catalina 10.15.6 (19G2021)) fails
to compile like so:

[...]

With the following patches applied to .../security/sslsplit compiling
went fine again:

Oh, I forgot: I had to use "env LIBPCAP_BASE=/opt/nb bmake"
as configure couldn't find libpcap (sorry, no patch for that).
