There are not many procedural statements to be used in Portfiles
(otherwise we are missing a necessary declarative abstraction):

Simply leave out the 'file mkdir ...' step.

The same rules as for a normal 'cp' on the shell apply here. When
copying a directory into a existing directory, you end up with a
subdirectory. If you specify a last path component that does not exist
yet, that is the name of the copied directory.
