Thanks! Now I get the log but I don't really understand what's going on:

/usr/bin/cc -dynamiclib -g -O2 -W -Wall -pedantic  -I/Library/Frameworks/Mono.framework/Versions/2.10.2/include    -Wl,-single_module registry.o util.o entry.o entryobj.o ../cregistry/cregistry.a -o registry.dylib -L/System/Library/Frameworks/Tcl.framework/Versions/8.5 -ltclstub8.5   -L/Library/Frameworks/Mono.framework/Versions/2.10.2/lib -lsqlite3

Apparently MacPorts picks up an SQLite library from an old Mono
installation on my machine. But why? And why only now, for the 2.0.4
update? And, most importantly, how can I prevent this?
