changes:
-bugfixes
-build framework modifications
-USE_LIBTOOL instead of .include libtool/buildlink
-add a patch to include <des.h> instead of <openssl/des.h> to make it
build with openssl-0.97 -- don't know whether this works with non-NetBSD
systems; if needed, a link into .buildlink/include should help
as mail/libesmtp.
Originally in PR#16146 from Alex Newman.
libESMTP is a library to manage posting (or submission of) electronic
mail using SMTP to a preconfigured Mail Transport Agent (MTA).
It may be used as part of a Mail User Agent (MUA) or another program that
needs to post electronic mail but where mail functionality is not
the program's primary purpose.
