[plt-scheme] Embedding MzScheme on Mac OSX

i am trying to embed mzscheme in my application and am useing this 
example here
http://download.plt-scheme.org/doc/103p1/html/insidemz/node6.htm
these lines arent compileing at all due to the scheme_config thingy
so i just threw out all other lines but
Scheme_Env *e = scheme_basic_env();

and i compile like this

gcc -I/Applications/PLT\ MzScheme\ v299.100/include -framework 
PLT_Mzscheme  test.c -o test

once i run this app it gives me a Segmentation Fault
