[tex4ht] TeX4ht upgrading: doesn't work

[celano]

Hello

here are the instructions to upgrade tex4ht (http://tug.org/applications/tex4ht/mn-upgrade.html).
It would seem quite easy, but doesn't work on my debian wheezy (testing) with TexLive2012 computer.


I follow every step and at point 6 (replace /usr/bin/tex4ht and /usr/bin/t4ht
with the new scripts downloaded on the website), the compilation fails.

Here is the message shown:

I tryed for a while to understand, but I didn't. Have you any idea?
Replacing the script t4ht works fine. Indeed, it doesn't work replacing tex4ht.

Thanks
