I am sorry but I am not able to access all successful and unsuccessful target platforms anymore.
I was getting these error messages for a few weeks now on platforms I do not own.
Therefore I waited with the report until I was able to get my hands on an unsuccessful platform.
Currently, I can only give you the output of this one.

I am sorry that the output was given in German on the target platform.
By using another Arch-Linux-based platform with a working build2 installation,
I got the same message translated into English.

  Using built-in specs.

For me, it does not really look like a wrapper.
