Unfortunately I'm not terribly familiar with WPMU, but I can tell you from a
PHP perspective that the code you posted won't work. The constant should
already be defined in wp-config.php (from what I understand) so you
shouldn't try defining it again (which is what the "constant" function
does). Instead, do something like this...

if(defined('VHOST') && 'yes' == VHOST)
  // do something for when blog addresses use sub-domains
else
  //do something for when blog addresses use sub-directories

As with many of my code snippets that I post on here, this is untested, and
YMMV, but if I understand how the VHOST constant works in WordPress MU (my
knowledge is admittedly limited to 20 minutes of Google searching), this
should be what you need.
