I upgraded all of my Apache 2 packages to the latest versions and disabled 
every module, re-enabling them one-by-one until I could get Apache to 
start up again. Enabling netcgi_apache breaks it as usual.

$ dpkg -l \*apache\* | grep ii

 failed!

I also tried apache2-mpm-worker and apache2-mpm-event - same problem. In 
all cases, libm was missing in the output of ldd /usr/sbin/apache2.

Thanks,
