[plt-scheme] module name clashes

I'd like to use the SRFI modules from the Schematics project, but it's
causing me some problems because it duplicates some of the stuff in
MzLib.  For example:

 > (module foo (lib "plt-pretty-big-text.ss" "lang")
      (require (lib "1.ss" "srfi")))
STDIN::338: module: identifier already imported (from a different source) at: third in: (require (lib "1.ss" "srfi"))

Now, I guess I could go through the two modules' `provide' statements
and figure out all the duplicate definitions and use `all-except' in a
`require' statement, but that seems pretty tedious (and fragile).  I
suppose I could get rid of MzLib's "list.ss" and require all the other
MzLib modules by hand, but again this is tedious, and what if I really
still want something provided by MzLib's list module that isn't
provided by SRFI 1?

What I think I want is a form of `require' (or something else) that
will override bindings that come from another module, rather than
complaining about them.  In other words, I want to say that I prefer
SRFI 1 above other modules if there are any conflicts.  Is this just
totally incompatible with the goals of the module system design?  What
other options do I have to deal with this problem?
