[plt-scheme] Creating a plt file

Hi there,

I am changing a plt file to install to a user specified directory as 
opposed to the add-ons directory. I am using:

(pack collection-file
          collection-name
          (find-files file-exists? "collects")
          (list (list collection-name))
          std-filter
          #t
          'file
          #f
          #f)

where collects is a directory containing my collection.

The plt gets created, but when I use DrScheme to install it none of  the 
collection files get compiled (they do get extracted). If I use

(pack collection-file
          collection-name
          (find-files file-exists? "collects")
          (list (list collection-name)))

The collection files do get compiled.

Is this the intented behaviour?
