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
Adding explicit error and description of php without prefork
Adding rspec-system tests for php + prefork
Merge pull request #225 from hunner/mod_php

Incorrect php .so
