[Mono-osx] Unable to compile app

[Mario De Clippeleir]

Hi,

I was working with Mono 2.6.3 on Leopard and my application compiled and 
was working (using mkbundle). I moved everything to Snow Leopard. Did a 
clean install of Mono Framework and its CSDK, but now i am getting 
always errors while trying to compile :

  [mkbundle] In file included from

etc....

Output of pkg-config --cflags -libs mono is :
-D_THREAD_SAFE -D_REENTRANT 
-I/Library/Frameworks/Mono.framework/Versions/2.6.4/include/mono-1.0 
-I/Library/Frameworks/Mono.framework/Versions/2.6.4/include/glib-2.0

  -pthread -L/Library/Frameworks/Mono.framework/Versions/2.6.4/lib 
-lmono -lpthread -lm -lgthread-2.0 -lglib-2.0 -lintl

Any ideas what's  causing this ?

Thx,
