Did we ever figure out custom 404 pages?

as a side issue, does anyone know how to use php to test if if php was compiled --with-curlwrappers ? Yes, php has a function that checks for installed extensions, but it just says "curl", and that's not good enough. phpinfo(1) could be used to bring in what php was compiled with, but since I am using a buffer already, I can't flush it just to test for curl wrappers. As usual, I'm probably making things harder than they have to be, so I hope Tominator has a great solution!
