wms.download and wms.request are internal from scripts/r.in.wms/

missing:
  mpeg_encode or ppmtompeg for r.out.mpeg

some of the above are optional
 (d.polar will work without xgraph, r.in.wms will work without xml2)

curl & wget are either/or
gardump & gpstrans are either/or and probably UNIX,Linux specific, respectively
GpsDrive is not ported to MS Windows so d.out.gpsdrive deps are low priority

All the C system() calls need to be searched too I guess.

Nope.
$ ogrinfo --formats | grep -ic xer
0
$ ldd `which ogrinfo` | grep xer
        libxerces-c.so.27 => /usr/lib/libxerces-c.so.27 (0xb76c0000)

as Xerces is apparently a XML parser not a vector format :)

You could try
$ gdal-config --dep-libs | tr ' ' '\n' | grep -ci xerces
1

but then gdal-config isn't always around. e.g. on Debian gdal-config comes with
the libgdal1-dev package and not the gdal-bin package. (and the libgdal1-dev
package depends on 18 other dev packages, which in turn depend on enough stuff
to make it a 20-50mb download just to run gdal-config. :-/ )

IIRC lynx is used to strip off HTML tags, ie to convert .html to .txt.

r.in.wms (wms.download) checks for wget. If it can't find it it then looks for
curl. (Apparently curl comes with MacOSX but wget doesn't)
So we wouldn't want to supply both.
