I attempted the same thing using a checkout from
http://bzr.xsteve.at/dvc/ (and my xemacs claims to be the same
version). I ran into most of your minor issues and some others
besides (see below), but eventually got a compiling dvc.

I didn't attempt to install dvc; instead, I just did
(load-file "/path/to/dvc/dvc-load.el"), pointing at the directory
where I had compiled using xemacs. Some things work: dvc-status
worked on an hg directory (and on dvc's source directory, under bzr),
and within that I could do 'e' for an ediff (although sometimes I'd
get an error about "display-buffer switched frames on its own!!").
But when I tried 'i' or 'c', I get:
Symbol's function definition is void: dvc-derived-mode-p.
This turns out to be unsurprising since dvc-derived-mode-p is defined
in dvc-emacs (only). Copying the definition over to dvc-xemacs.el
seems to get rid of that error. But there are other problems; for
instance, xhg-push fails with an error about try-completion. I
haven't pursued this further, but perhaps it's of some use to others
trying to get dvc working in XEmacs.
BTW, here are the additional changes I had to make to the
source for XEmacs to compile it:
* In dvc-build.el, I had to add (load-library "cl-macs").
* I had to change several 'ecase' calls with 't' cases to be 'case'.
* I was building in a different directory from the source, and I had
to copy over two files (texinfo/dvc-intro.texinfo and
lisp/custom-load.el) from the source into the corresponding
compilation directory. (I have to do the first copy even if setting
up dvc for emacs.)
