This isn't the same location that I have on Linux (RedHat installs it in
/usr/bin). I can't help but wonder if it doesn't find the right .pm
file(s)...
Try running latex2html under "perl -w" -- see if the warnings are
informative...

One other question: I don't recall you posting your cygcheck output (see
<http://cygwin.com/problems.html>). In particular, do you have Visual
Studio installed? It sometimes sets the INC environment variable, which
screws up perl.
