This means that there is a mismatch between the TeX engine that
created  latex.fmt  and the TeX engine that you are running
for the current job...

  ... which is now pdfeTeX.

So  ldump.sty  probably needs to be modified to be loading
  latex.efmt  instead of  latex.fmt ,
and then build on top of that for its specialised format
  ---  which may also need to be named with .efmt  as the
filename suffix.

That's the easy part.
It means:
   "you asking asking me to use stuff that probably will not work
  anyway, due to some kind of mismatch, so I'm not even going to try".


The medium part is to find out what the corresponding resources are
now called, and where to find them in the TeX hierarchy.

The harder part is to adjust the various packages (ldump.sty)
and scripts (part of LaTeX2HTML) so as to recover the ability
to have it all work correctly, in a fully automated way.

There is some history behind that, which I won't try to explain here.

You could try adding the following to your LaTeX preamble:

\usepackage{color}
\pagecolor{white}

Transparency should work with .gif images, but may not with .png format.
This could be dependent upon which browser you use to view the HTML 
pages.



Hope this helps,
