teTeX has only pzdr.tfm. See below for reasons.

I can explain it once again. In 2003 all that urw mess was hopefully
cleaned on CTAN and then on TL. Discussion started on 6 june and on 
24 july that's me, who cleaned it for TL. The *base* 35 urw fonts (only
afm and pfm/pfb) were prepared *after* all that urw tfm, vf etc. support
files were made.

>From README.base35
  TeX systems can use these fonts as drop-in replacements for
  Adobe's PostScript Base fonts, which are not free.  No
  particular TeX metrics, virtual fonts or macro files are
  provided for URW's base fonts.  They are to be used with the
  same support files as Adobe's originals, i.e., with the
  files of the PSNFSS collection.

  AFM and PFM files are supplied here for the sake of
  completeness only.  They are normally not required for use
  with TeX.

In fact, nobody knows how the *old* mess with tfm, vf etc. fits
to more *new* urw pfb which are of better quality then the older ones. 
Anyway both distributions cannot be mixed. Not to say about packaging, etc.
So I introduced "urw35vf" (#3416) which contains all (historical) stuff
for those using urw fonts directly (.vf, .tfm, .fd, .sty files).
Everybody has freedom using them from TL. Thomas removed such stuff
from teTeX as simply garbage.

??? Everything is OK: fonts/afm/urw/ and fonts/type1/urw/

They are as well present in teTeX.

Ahh, I see! aliases could cause problems. Thanks for deleting that file.
