When compiling latest WebKit2 under Ubuntu 11.10 I was facing some errors with SharedMemoryUnix.o. 

/home/luck/work/webkit/WebKitBuild/Release/Source/WebKit2/release/libWebKit2.a(SharedMemoryUnix.o): In function `WebKit::SharedMemory::create(unsigned long)':
SharedMemoryUnix.cpp:(.text._ZN6WebKit12SharedMemory6createEm+0x1fb): undefined reference to `shm_open'
SharedMemoryUnix.cpp:(.text._ZN6WebKit12SharedMemory6createEm+0x30e): undefined reference to `shm_unlink'
SharedMemoryUnix.cpp:(.text._ZN6WebKit12SharedMemory6createEm+0x459): undefined reference to `shm_unlink'
collect2: ld returned 1 exit status

After some investigation we find out that the problem was related to linker parameter's order. -lrt should come after -lWebKit2. I'm attaching a patch that ensures the right order of these parameters.
