[plt-scheme] Most recent mzc b0rked on compile-subcollections in infotab

I've tried to compile PLT Scheme from a recent (yesterday,
I think) svn checkout.  It is currently breaking on the
compile-subcollections statement in the science
collection's info.ss. 

Here's the definition of compile-subcollections in the 301
mzc manual:

compile-subcollections -- a list of sub-collection
sub-paths, where each sub-path is a list of strings; each
full sub-collection path is formed by appending the
sub-path to the path of the collection being compiled. Each
sub-collection is compiled in the same way as the current
collection, using the info.ss library of the
sub-collection. This information is optional.

Here's the value in the info.ss:

(define compile-subcollections
    (list (list "special-functions")
          (list "random-distributions")))


Here's the error message:

build-path: expects type <path, string, 'up, 'same> as 2nd
argument, given: ("special-functions"); other arguments
were:
#<path:/home/pg/nhw/.plt-scheme/planet/300/300/cache/williams/science.plt/2/0>


There is this is compiler-unit.ss in the compiler
collection:

(when (compile-subcollections)
                (for-each
                 ;; bug! planet files will do the wrong
thing here
                 (lambda (s)
                   (unless (and (pair? s) (list? s) (andmap
string? s))
                     (error 'compile-collection "bad
sub-collection path: ~a" s))


So perhaps this bug is known and being worked on.
