I think the path of netpbm tools are not set correctly because 
pstoimg script should do: 

  /usr/local/bin/pnmcrop -verbose  < /tmp/l2h1930/p4047.pnm 
  | /usr/local/bin/pnmcrop -verbose  -bot  -sides 
  | /usr/local/bin/pnmcrop -verbose  -l  -sides   
  > /tmp/l2h1930/p4047.t00

where netpbm tools are in /usr/local/bin. There seems to be two 
solutions.

[a] Re-install latex2html after setting

  set path = ( [netpbm binary path] $path )

on csh|tcsh, or 

  PATH=[netpbm binary path]:$PATH ; export $PATH

on sh|bash.

[b] Setting the variables $PNM* of lib/latex2html/l2hconf.pm
and bin/pstoimg directly. For example:

lib/latex2html/l2hconf.pm:
 $PNMCUT = '/usr/local/bin/pnmcut';
 $PNMFLIP = '/usr/local/bin/pnmflip';
 $PNMPAD = '/usr/local/bin/pnmpad';
 $PNMROTATE = '/usr/local/bin/pnmrotate';
 $PNMSCALE = '/usr/local/bin/pnmscale';

bin/pstoimg:
 # Netpbm
 my $PNMCROP = '/usr/local/bin/pnmcrop -verbose ';
 my $PNMCROPOPT = ' -sides ';
 my $PPMQUANT = '/usr/local/bin/ppmquant';
 my $PNMFLIP = '/usr/local/bin/pnmflip';
 my $PNMCAT = '/usr/local/bin/pnmcat';
 my $PNMFILE = '/usr/local/bin/pnmfile';
 my $PBMMAKE = '/usr/local/bin/pbmmake';
 # GIF support
 my $PPMTOGIF = '/usr/local/bin/ppmtogif';
 # PNG support
 my $PNMTOPNG = '/usr/local/bin/pnmtopng';
