Hi Radim,

I tried building today on OS X. The build failed with the following output:
[ 20%] Building CXX object src/analysis/CMakeFiles/qgis_analysis.dir/qgsrastercalcparser.cpp.o
Linking CXX shared library libqgis_analysis.dylib
[ 20%] Built target qgis_analysis
[ 20%] Generating analysis/sipanalysispart0.cpp, analysis/sipanalysispart1.cpp, analysis/sipanalysispart2.cpp, analysis/sipanalysispart3.cpp

sip: /Users/jctull/sources/qgis/raster-providers/python/core/conversions.sip:326: %MappedType template for this type has already been defined
make[2]: *** [python/analysis/sipanalysispart0.cpp] Error 1
make[1]: *** [python/CMakeFiles/python_module_qgis_analysis.dir/all] Error 2
make: *** [all] Error 2

I have no such problem building from a fresh copy of qgis trunk.
