Stephan,
Comparing to a good workdir/UnpackedTarball/librevenge/config.log,
This seems to be the problem:

Any ideas what's going wrong?

You'd need to look into workdir/UnpackedTarball/librevenge/config.log to 
see why compiling the test source containing


  #include 

fails.  (The symptoms look similar to 
 "[10 Regression] 
ICE in linemap_macro_map_loc_to_exp_point, at libcpp/line-map.c:1061" 
which I encountered in external/libetonyek, but that was with GCC not 
Clang.)

Clang trunk build failure in external/librevenge

[Luke Benes]

After commit: http://llvm.org/viewvc/llvm-project?view=revision=360308

Clang builds are failing on both Arch and Ubuntu with the following error:

checking for boost/spirit/include/classic.hpp... no
configure: error: Required boost headers not found.
make[1]: *** [/core/external/librevenge/ExternalProject_librevenge.mk:23:  
/core/workdir/ExternalProject/librevenge/build] Error 1
make[1]: *** Waiting for unfinished jobs
32 warnings generated.
114 warnings generated.
40 warnings generated.
make: *** [Makefile:282: build] Error 2

Does this look like a compiler bug or issue with our build system?
