Wt

Hello everyone.
I use gcc 4.4.5 on debian 6.1 and cmake version 2.8.2.
I noticed an compilation error

[ 79%] Building CXX object test/CMakeFiles/test.dir/dbo/Benchmark.o

The error shows up, if the packaged version of boost is installed,
but the cmake wt script has been run with:
cd wt
mkdir build
cd build
cmake -DBOOST_ROOT=/root/work/boost_1_47_0 -DCMAKE_INSTALL_PREFIX=/usr ../

Temporary fix:
remove the debian packaged boost (developer version) with:
aptitude unmarkauto "?name(gccxml)"
RECHECK YOUR APTITUDE OUTPUT TWICE!!! So that you do not delete other dependecies who are neded for compiling wt. They can be ignored for autoremoval with aptitude unmarkauto.
aptitude purge "?name(libboost1.42)"

I think this is a error within the wt cmake script which uses system include paths before custom set paths.
I currently have not much time to investigate this error further, but on the next Weekend I can go on with it.
Greetings Louis
