Actually, it *is* an upstream bug. But I can reproduce it only with
a separate build directory (this is what Debian does). I suppose
that the path to the .trm files is incorrect in such a case.

doc2texi.el has

(defvar d2t-terminal-directory (expand-file-name "../term/")
  "Location of .trm files in gnuplot source tree.")

If I understand correctly, this is relative to the build directory
(since the current working directory is there), while this should have
been relative to the source directory. A general fix is not obvious:
one would have to pass $(srcdir) to the file, unless there is some
Emacs variable that already contains the information. However, for
Debian, the build directory is at some fixed place in the source tree,
so that this can be fixed by just adapting the relative path.

Patch attached.
