define-obsolete-face-alias error when opening a file

When DVC is enabled I get the following error when I try to open a file:

'eval-buffer: Symbol's function definition is void: define-obsolete-face-alias'

It doesn't seem to matter what file I am opening or the mode. I've had
the error when opening my .emacs file, a file using CPerl mode, and a
file using Fundamental mode. The weird thing is that if I try to open
the file a second time, it works. It seems that the DVC commands work
correctly once I get the file loaded.

I have flyspell, and perltidy enabled, but I get the error even if I
disable them. I'm using Emacs 23.0.60.1 on ubuntu.

Thanks

That's weird:

dvc/moy$ grep -irn obsolete **/*.el
lisp/tla.el:2517:  (dvc-trace "OBSOLETE")
lisp/tla.el:2543:  (dvc-trace "OBSOLETE")
lisp/tla.el:3582:(defun tla-bookmarks-load-from-file-OBSOLETE (&optional force)
lisp/tla.el:3609:             (tla-bookmarks-load-from-file-OBSOLETE force)))))

On my Emacs 21.3.5, I have

Emacs 23

Emacs 23.1 is released; I've switched to using it.

The byte-compiler now warns about using the Common Lisp runtime.
Compiling DVC gets many warnings, mostly in xmtn.

I will work on eliminating CL runtime from the xmtn packages; that
will take a lot of work.

(I don't consider these very important, but it's good to follow the
guidelines ...)

Most of the 'cl things are actually macros, so first thing you can do
it to replace

(eval-and-compile (require 'cl))

by just (eval-when-compile ...).

Then, the warnings I get are :

Warning: Function `gensym' from cl package called at runtime
Warning: Function `subseq' from cl package called at runtime
Warning: Function `gensym' from cl package called at runtime
Warning: Function `some' from cl package called at runtime

gensym => see `dvc-gensym', they should be similar.

Thanks for your work,

There is a bug in the xmtn code somewhere that causes a 'c' or 'C-c'
key event to be generated, intermittently. I suspect that is due to
the CL runtime; the bzr code doesn't exhibit the same bug, and the
main difference is the CL runtime (assuming the external process
running mtn isn't the problem!).

The reason the CL runtime is deprecated is that it has bugs. So we
should not use it.

I generally find fixing warnings to be a good thing. There are always
exceptions, so it would be nice if we could tell the byte compiler to
shut up in specific instances, like dir-compare in dvc-fileinfo, and
captured-values in dvc-lisp. In those cases, we could declare a global
variable, but that seems wrong.

It's used also in the `dvc-capturing-lambda' stuff in dvc-lisp.el.

I don't remember (one could play with the old GNU Arch archive to see
the history of the code, but it's revision 1 in the bzr archive).

Google tells me other alternatives:
