Thanks a lot for saving us from the horrors of redland.
But: I just did a fresh svn checkout of http://svn.drobilla.net/lad/trunk
and tried a top-level build (./waf configure && ./waf build) which fails miserably
complaining about:

  Waf: Entering directory `/Development/drobillard/build'
[  8/434] cxx: plugins/lolep.lv2/src/LV2Plugin.cpp -> build/plugins/lolep.lv2/src/LV2Plugin.cpp.5.o

../plugins/lolep.lv2/src/arith.cpp:22:51: error: lv2/lv2plug.in/ns/ext/uri-map/uri-map.h: No such file or directory

 ... and so on. Is this expected?
