[plt-scheme] Inter-extension dependancies

Hi,

I have 2 sets of extensions linked as shared libs (A and B). A uses some
functions from B.

So I (load-extension B) first. When I try to (load-extension A),
mzscheme complains that it cannot find the symbol which was actually
loaded as part of extension B. What gives? Is there any way to achieve
the above without compiling them both into 1 monolithic extension?

Thanks.
