opensuse11.1-64位系统下面编译rtorrent ?

zpcat

开始./configure提示没有libtorrent，可我明明安装了，于是找到是pkg-config的问题原来它默认只搜索/usr/lib64/pkgconfig/里面的文件，于是我把/usr/lib/pkgconfig/libtorrent.pc拷贝到上面的目录。configure通过了。
但是，make报错：
text_element_value.cc: In member function ‘virtual char* display::TextElementValueBase::print(char*, char*, std::vector<display::Attributes, std::allocator<display::Attributes> >*, rpc::target_type)’:

大家看看难道64位的系统不兼容32的软件吗？（我在32位的suse10.3中轻松编辑过此软件）
以上错误如何解决呢？
