[plt-scheme] scheme inside c++

i tried to do this:

http://www.godpatterns.com/article/embedding-scheme-in-c/

on mac osx,

and compiled like this:

g++ blah.cpp -I/coding/PLT\ Scheme\ v4.1.4/include/ /coding/PLT\ Scheme\
v4.1.4/lib/PLT_MzScheme.framework/PLT_MzScheme

and then set this:

export DYLD_LIBRARY_PATH=/coding/PLT\ Scheme\
v4.1.4/lib/PLT_MzScheme.framework/

and then got an un-smiley face back from my mac:

./a.out #f::0: compile: unbound identifier (and no #%app syntax transformer
is bound) at: + in: (+ 1 1)
Seg fault (internal error) at 0x4
Bus error

--------

anyone mess around with this before?  bear in mind i don't really use my mac
for much more than surfing the web.  I think if I get another, I'll format
it with linux.

Thanks.
