I can't find that error message anywhere in the current sources.
That would seem to indicate that you're using an older version -
perhaps the problem you're having was fixed at the same time the
error message was removed (or at least spell checked ;)).

The output of ppmtoy4m will place a header containing the size
information in the file. On one of the .y files do a "head -n 1"
and you should see something similar to
YUV4MPEG2 W720 H480 F30000:1001 Ib A10:11
If not then the creation of the .y file wasn't correct - could
be a bug jpeg2yuv that's been fixed since the version you're
using.
A release candidate is being worked on now so if trying the cvs
version isn't of interest then waiting a few days for the next
tarball might be a good idea.
