Installing mod_auth_openid on Debian Etch
I followed the directions here.
This seems to work on Debian Lenny, but there is a world of unmet dependencies for Debian Etch.
apt-get update apt-get install libopkele-dev
I also had to install a generic package not already installed on my system:
apt-get install automake
Then pull in the libdb dev package:
apt-get install libdb4.4++-dev
Then, download the source from http://butterfat.net/wiki/Projects/ModAuthOpenID/Releases.
./configure make sudo make install
