 Well, those lines are in both system files, but it turned out that
 /opt/local/include/uuid/uuid.h did not contain them. I temporarily renamed
 the one in /opt/local and then pkgconfig built without problems. Thanks
 for the hint to check those files and for your help with this issue!

 Follow-up question: can I simply remove the uuid.h in /usr/local/include?
 Does macports usually install its own version in there?
