I would recommend that you read the test scripts and determine exactly why they're failing. Only when you understand that, and know whether they're failing for valid reasons or not, should you force the install.

I don't know why that particular module's tests might be failing (I don't have Apache installed, so I can't check), but it could well be failing for a good reason. OTOH, I've had at least one module (Net::Server, specifically) that failed a test for no good reason (I was installing it on win32 and the tests used alarm though none of the module code actually relied on alarm), and forcing the install allowed the module to work fine.

The tests are there for a reason, and you shouldn't just blindly ignore them when they're reporting a problem. :)

Update: Once you've started / tried to install the module, the tests scripts are located in your CPAN build directory, usually ~/.cpan/build/<module filename>/t/
