Since tests have more dependencies than phpbb proper, it would be useful to have a script that checks for the presence of test dependencies. It would also report which part(s) of the test suite are runnable given installed dependencies.

Things to check that I can think of now:

• ctype
• date.timezone php ini setting
• pdo
• pdo drivers
• sqlite 2 (vs 3)
• pdo_sqlite2
• permissions?
