[Swan] problem command "ipsec verify"

[Jorge Sevillanos]

Hi Bruno, something weird is happening.

Amazon Linux 2 by default comes with python2 & python3 installed and their
executables are  inside /usr/bin

If I execute "ipsec verify" inside this PATH: "/usr/bin" , ipsec command
works perfectly.

But if I execute  "ipsec verify" in another PATH that is not inside
"/usr/bin", the bad interpreter comes out:

Also check the path for command python and python2:

I also tried to install another version of LibreSwan, 3.32, 4.1 and 4.2,
Version 3.32 and 4.1 worked super but versions 4.2 and 4.4 have this issue.

How can this be fixed?

Regards,

Rodolfo
