Speaking of trace mode, it doesn't work for me. Fails during extract  
already:

The problem seems to be that darwintrace.dylib is compiled for i386  
only but my bzip2 is 4-way universal. If I deactivate bzip2  
+universal and install bzip2 non-universal it extracts fine.

So for darwintrace to work with 4-way universal ports, I need to  
build MacPorts base as 4-way universal? I have tried, but I get:
