AFAICS, ignore_commands is defined in the latex2html script itself.
There's probably another reason for this problem.

Is the file l2hconf.pm readable?  Is it in the default install directory
(/usr/share/latex2html)?  If not, is the directory that contains it in
perl's include path?

Try copying l2hconf.pm to the current directory, and putting print
statements in it to track the progress of its loading (you'll need to set
L2HCONFIG to "./l2hconf.pm").  Don't forget to set $|=0 in the beginning
to turn off buffering.
HTH,
	Igor
