Installation of Bacula

[Rajstopy]

Dear TrueNAS users,

I'm really struggling with trying to install Bacula in a jail (FreeBSD Bacula 13.1-RELEASE-p7 FreeBSD 13.1-RELEASE-p7 n245428-4dfb91682c1 TRUENAS amd64).
I've tried using Ports but this way leads to an error :

Code:

Configure: Fatal Error: /usr/sbin/dtrace doesn't support -h flag

I've also tried using pkg but did not find any documentation to get it well configured...

Before digging further into that, has anyone a running Bacula installation in a jail, on what is the best way to achieve the setup?

Cheers,
R.
