cc1: warnings being treated as errors
/home/acme/Tools/libreswan-4.1/lib/libswan/secrets.c: In function ‘RSA_sign_hash’:
/home/acme/Tools/libreswan-4.1/lib/libswan/secrets.c:319: error: implicit declaration of function ‘PK11_SignWithMechanism’
/home/acme/Tools/libreswan-4.1/lib/libswan/secrets.c:319: error: nested extern declaration of ‘PK11_SignWithMechanism’

PK11_SignWithMechanism() was added to nss 3.22. It looks like your nss
version is too old ?

It might be that libreswan 3.29 and older don't use PK11_SignWithMechanism() so you could try
an older version, but obviously it is better to see about upgrading nss.
