- In Configure, register the perl interpreter used to run Configure, so that's the one being used throughout instead of something else that Configure happens to find. This is helpful for using a perl version that's not necessarely first in $PATH: /opt/perl/5.22.1/bin/perl ./Configure - Make apps/tsget a generated file, just like apps/CA.pl, so the perl interpreter registered by Configure becomes the hashbang path instead of a hardcoded /usr/bin/perl Reviewed-by: Andy Polyakov <appro@openssl.org>
