You're likely not able to access a custom php.ini file. But ask your host if there is any solution here - who knows what their set up is.
Other people will have to help here, but I believe you can put some PHP directives in the .htaccess file, possibly? But this probably won't help as if it is a similiar issue to mine it'll be a problem with the server's php.ini file having a faulty character or something like that.
It's a real nasty issue huh. Just another one of those things when you're dealing with many interconnected open source products :)
You're best bet might be to copy/paste them my solution and frame it like: It's highly likely there is a problem with your PHP configuration, could you please check to make sure there are no extra tabs/spaces or other issue with the register_argc_argv statement.
