Hm, there already seems to be a check for it in the configure.ac to
turn off the xscope dependency, but it seems someone didn't consider
that when changing code.

I'm not comfortable changing that because I don't know enough about
the tool or xtrans, so perhaps someone familiar with xscope can try
building with xtrans disabled and fix the fallout?
