I get the following problem when trying to build latest (CVS) version of 
GDC with enabled D2 support. Attached is my config.log.

checking If /root/src/build/./gcc/gdc -B/root/src/build/./gcc/ 
-B/opt/gcc/i686-pc-linux-gnu/bin/ -B/opt/gcc/i686-pc-linux-gnu/lib/ 
-isystem /opt/gcc/i686-pc-linux-gnu/include -isystem 
/opt/gcc/i686-pc-linux-gnu/sys-include can compile D sources...

`GCC_4.2.0' not found (required by /usr/lib/libstdc++.so.6)
no
configure: error: can't compile D sources!
make[1]: *** [configure-target-libphobos] Error 1
make[1]: Leaving directory `/root/src/build'
.

I'll try to fix this problem myself, but I am kinda confused with that 
"GCC_4.2.0" - I have GCC 4.1 on my Linux box! :)

Kind regards

Common problem. Do a `make distclean` (or even better, remove your build 
directory entirely), then configure with the options --enable-static 
--disable-shared. The problem is that it's getting system libraries 
confused with local libraries. Forcing it to make them all static 
eliminates this possibility.

Although you may have GCC 4.1 installed, the version of the GCC 
libraries (and libstdc++) is usually 4.2 on a modern system, because 
it's backwards compatible but 4.1 isn't forwards compatible. It only 
causes problems in particularly strange situations like this one.

Thank you Gregor, it works now.
