I also meet with another DSO issue when compiling the libva staging
branch on Fedora 15. The following is the corresponding error: 

make[3]: Entering directory `/root/gen_gfx/libva/test/encode'
  CC     avcenc-avcenc.o
  CCLD   avcenc
/usr/bin/ld: avcenc-avcenc.o: undefined reference to symbol
'pthread_create@@GLIBC_2.2.5'
/usr/bin/ld: note: 'pthread_create@@GLIBC_2.2.5' is defined in
DSO /lib64/libpthread.so.0 so try adding it to the linker command line
/lib64/libpthread.so.0: could not read symbols: Invalid operation
collect2: ld returned 1 exit status
make[3]: *** [avcenc] Error 1
