pyblosxom on lighttpd

Hi developers.

On lighttpd, I can't access archive page,
like http://localhost/pyblosxom.cgi/2005/Dec/09 .

When I run it renderer debug mode on apache and lighttpd,
result is different. Looks like, lighttpd change path info
to lower character, so month value is not match for tools.MONTHS.

* lighttpd

  pi_bl -> /2006/dec/09
  pi_da ->
  pi_mo ->
  pi_yr -> 2006

* apache

  pi_bl -> /2006/Dec/09
  pi_da -> 09
  pi_mo -> Dec
  pi_yr -> 2006
