at this point, i think it has something to do with my build of gcc,
because our versions dont look all the different, but i'm no expert

$ gcc -v
Using built-in specs.
Target: i386-redhat-linux
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man

--disable-libunwind-exceptions --enable-libgcj-multifile
--enable-java-awt=gtk --disable-dssi --enable-plugin
--with-cpu=generic --host=i386-redhat-linux
Thread model: posix
gcc version 4.1.2 20070626 (Red Hat 4.1.2-13)
