Then there is something broken with your build/install of gcc-3.4. GCC 
adds the required references to it's internal libraries. If the 
libraries are close relatives of the default system ones then you might 
need to set your LD_LIBRARY_PATH to point it elsewhere.

You can by specifying the BUILD request as such: 
"-sBUILD=<linkflags>-Wl,-rppath,/usr/local/gcc_3.4/lib"...

But I would recomend against it. It ties the executable to that 
location. It's better to set up the LD_LIBRARY_PATH correctly.

HTH.
