According to the OpenSSL-core-team you are strongly encouraged to upgrade
any old version. The new version has a lot of bug fixes.
- ${PREFIX}/bin/ssleay was renamed to ${PREFIX}/bin/openssl and
${PREFIX}/etc/ssleay.cnf to ${PREFIX}/lib/openssl.cnf
- there are no links from e. g. ${PREFIX}/bin/md5 to ${PREFIX}/bin/ssleay
any longer, instead you have to call "openssl md5" now
- replaced HAS_CONFIGURE, CONFIGURE_SCRIPT and CONFIGURE_ENV with a
do-configure target and changed the indention level
- some perl scripts need perl5 now, so set USE_PERL5 and replace perl
with ${PERL5} where neccessary.
- honour ${CFLAGS}
