Well, I have found that undefined non-weak symbols are in libstdc++.so.
Actually, unless this is fixed, I cannot compile the following:

[tasaka1 at localhost PROGRAM]$ g++ -O2 -o itpp-check itpp-check.cpp -litpp -nostdlib 
[tasaka1 at localhost PROGRAM]$ cat itpp-check.cpp
int main(){
  return 0;
}
[tasaka1 at localhost PROGRAM]$ g++ -O2 -o itpp-check itpp-check.cpp -litpp -nostdlib
/usr/bin/ld: warning: cannot find entry symbol _start; defaulting to 080481c0
/usr/lib/gcc/i386-redhat-linux/4.1.1/../../../libitpp.so: undefined reference to
`std::runtime_error::runtime_error(std::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&)'
/usr/lib/gcc/i386-redhat-linux/4.1.1/../../../libitpp.so: undefined reference to

Explicit linking against external libraries are always needed when
header files in the library use some types, 
structure or so which are defined by other packages then the
header files include other external header files.
( I have not checked if this package falls under this case).
