Where's debug.log?

I am having a huge amount of hassle trying to build PHP 4.3 with Sablotron 0.96.1 When I look in config.status, I see the following message. if test -n ""; then

    rm -f config.cache

cat <<X +--------------------------------------------------------------------+

|                       *** ATTENTION ***                            |

| Something is likely to be messed up here, because the configure    |

| If you are unable to fix this, send the file debug.log to the      |
| php-install@lists.php.net mailing list and include appropiate      |
| information about your setup.                                      |

X fi The only problem is I don't have a debug.log file to send in. Is there something I need to do to activate this feature? I sent in my configure script to this list yesterday, so you can see what parameters I tried to use. Any help would be greatly appreciated. Thanks, Dean Dahnke
