[l2h] pnmtopng image convertion

[Aline da Rocha Gesualdi]

I'm having problems in creating images for the formulas in latex2html. This 
error always occurs:

My version of latex2html is latex2html-2K.1beta and my opperational system 
is Linux Conectiva 6.0
I tried to install libpng 1.2.1, zlib 1.1.3 and netpbm release 9.9, but 
some errors occurs during the installation.

Does anyone know how to install the pnmtopng and pnmcrop in order to make 
latex2html works?

Erros in the instalation of netpbm release 9.9:
