Staden install on Mac OSX 10.6

[andreitudor]

Hello,
I am trying to install staden on mac osx 10.6. I have successfully installed everything with macports, and have configured with the appropriate options. But when I $sudo make I get this error:

tkTrace.c: In function ‘drawable_to_png’:
tkTrace.c:2126: error: dereferencing pointer to incomplete type
tkTrace.c:2131: error: ‘Z_BEST_COMPRESSION’ undeclared (first use in this function)
tkTrace.c:2131: error: (Each undeclared identifier is reported only once
tkTrace.c:2131: error: for each function it appears in.)
make[1]: *** [tkTrace.o] Error 1
make: *** [tk_utils] Error 2

Is there a way to fix this? I have tried with 2.0.0b7 and b8. Same thing happened with both...
