The ErrorLog issue only happens under mod_perl. Given that all logs
were in the appropriate directory but I went and checked and it is set
appropriately in apache2/envvars. If you look at the snippet of my
configuration file you will see I set the error log just before setting
up mod_perl.

Thank you that is useful. I will look into that. I have gotten that
file. Is there some documentation to go with it?

Thank you. That is helpful too.
