new libwnck make emerald fail to start

[Ken YANG]

hi all,

i am using fc8 rawhide, and with libwnck:

libwnck-2.19.3-2.fc8

but emerald fail to start, it need libwnck-1.so.18,
so i use a trick to pass this error:

ln -s libwnck-1.so.21.0.0 libwnck-1.so.18

i think emerald should be compiled with new libwnck
