Bottom (i.e., innermost) frame selected; you cannot go down.

FreeBSD 11.1 and 11.2 RELEASE are effected.

On a personal note I would love to get this running so I can run VMs in GNS3 2.0.3!

For the time being it has been solved. I just need to dig more with the issue. The CMAKE environment variables were not properly passed to the build environment which have been fixed. But need to dig more.
