[gccsdk] Building libssh2 fails while building nettle with the autobuilder. Any clues?

I would like to be able to build !Nettle as I would like to see if I can add public/private key authentication to it.

I have never used the auto builder before and I am at a bit of a loss to know where to start with the error that it presented while building libssh2.

 

Along the way:

 

Autobuilder: source directory is /home/alan/build/libssh2/libssh2-1.5.0

Autobuilder: Debian patch: 0001-Add-lgpg-error-to-.pc-to-facilitate-static-linking.patch

That looks to me like a disparity in expectations between static and dynamic builds for ‘tests’ but I couldn’t see how or where to influence that.  I presume that even if it can build them it can’t run them anyway.

 

Thanks in advance to anybody to suggest how to deal with this.
