Acho que consegui compilar o source que tinha na pasta /home/asea/Documents/Files/Source/build/src

2 man subdirectories contained newer manual pages.
86 manual pages were added.
0 stray cats were added.
0 old database entries were purged.
You now need to run 'sudo make setuid' in order to run in place.
make: Leaving directory `/home/asea/Documents/Files/Source/build/src'
root@asea-desktop:/home/asea/Documents/Files/Source/build/src# sudo make setuid
make: Entering directory `/home/asea/Documents/Files/Source/build/src'

This script only needs to be run once per shell session.

LINUXCNC - 2.5.4
Application initialization failed: no display name and no $DISPLAY environment variable

Agora tem que verificar localmente, visto que pelo ssh não consigo acessar o driver de vídeo. Acho que precisavam dar um make clean antes de compilar de novo.
