apache::mod::php needs a custom lib for Debian and Ubuntu
ah, php is not compatible with apache::mod::worker, and requires apache::mod::prefork
mpm_module must be prefork for mod_php

....need to figure out the 'failed' test
borrowed precondition from prefork
I prefer 'prefork' it's explictly what's desired here.
update description and expected library string
Update README, without destroying whitespace.
remove require call, and use metaparameter instead
Merge pull request #5 from nesi/mod_php

Allow mod PHP to work on Ubuntu
