No, for instance sqlite3 link just fine. It may be more clear in the  
following log where we can see that Wm3::String::operator unsigned  
int() const seems to be defines 2 times :

I had compiled a version of gcc with openmp support (it was very long!).
here is the version:

$ g++ -v
Using built-in specs.
Target: i386-apple-darwin9.8.0
Configured with: ../gcc-4.3.4/configure --prefix=/opt/local --enable- 
languages=c,c++,objc,obj-c++,java,fortran --libdir=/opt/local/lib/ 
gcc43 --includedir=/opt/local/include/gcc43 --infodir=/opt/local/share/ 
info --mandir=/opt/local/share/man --with-local-prefix=/opt/local -- 
with-system-zlib --disable-nls --program-suffix=-mp-4.3 --with-gxx- 
include-dir=/opt/local/include/gcc43/c++/ --with-gmp=/opt/local --with- 
mpfr=/opt/local
Thread model: posix
gcc version 4.3.4 (GCC)

and I added a symbolic link:

$ which g++
/usr/bin/g++
$ ls -al /usr/bin/g++
lrwxr-xr-x  1 root  wheel  25  1 sep 21:24 /usr/bin/g++ -> /opt/local/ 
bin/g++-mp-4.3

Unfortunately, scons fails at check level:

$ scons

Your compiler is broken, no point in continuing. See `/Users/richefeu/ 
Documents/yade-local/build-vr/config.log' for what went wrong and use  
the CXX/CXXFLAGS parameters to change your compiler.

I think no... but I will investigate the matter.

Tomorrow, I will try to compile the complete Wm3 separately.
Thank you for help Vaclav. Has you know, compiling a soft on several  
OS make it more robust.
