Thanks for answering Parv.

I have a Phedora Core 2 system where latex2html works fine.
It uses netpbm-9.24 not netpbm-10.24 as FreeBSD does.

So... forced FreeBSD to uninstall netpbm-10.24, and
then downloaded and compiled netpbm-9.24.

It is a little tricky because netpbm does not supports
FreeBSD, so I took "openbsd" option and changed the
Makefile.config to fulfill FreeBSD requirements.

Once it was installed, latex2html worked fine.

Now, I do not know what to think.
Either,  latex2html is trying to use options that
do not work with netpbm-10.24, or netpbm-10.24 does
not work properly.

I think this deserves a report.

Thanks for your help.

	Eduardo.
