problem compiling terragear

Hi,

I am having problems building Terragear-0.0.5.
It says that terragear requires simgear-0.3.0 which can't be built ( 
found that from mail archives). So, I used the latest version of simgear 
i.e. (0.3.4)to build Terragear. I could debug a few problems but not 
this one.


../../../src/Lib/Geometry/libGeometry.a(util.o)(.text+0x1746): In 
function `tg::parseChunk(std::basic_string<char, std::char_traits<char>, 
std::allocator<char> > const&)':
/usr/include/c++/3.2.2/bits/stl_alloc.h:664: undefined reference to 
`sg_exception::sg_exception[in-charge](std::basic_string<char, 
std::char_traits<char>, std::allocator<char> > const&, 
std::basic_string<char, std::char_traits<char>, std::allocator<char> > 
const&)'

Can anybody please help me.

thanks
