Step 7 error

Hi, I'm experiencing the following error on step 7 of the install. Any suggestions? Thank you for your help (amazing I could customize the heck out of Gallery 1.x and now that we have a nice installer I'm stuck!).

Warning: requireonce(/home/httpd/vhosts/gainesvillejaycees.com/httpdocs/gallery/modules/core/classes/GalleryPlatform/UnixPlatform.class): failed to open stream: No such file or directory in /home/httpd/vhosts/gainesvillejaycees.com/httpdocs/gallery/modules/core/classes/GalleryCoreApi.class on line 2344

Khem.
