uvc driver 在make時出現 NO rule to make target 'modules' .stop

make 時
出現
Building USB Video Class driver...
make[1]: Entering directory `/usr/src/kernels/2.6.18-1.2798.fc6-i586'
make[1]: *** No rule to make target `modules'. Stop.
make[1]: Leaving directory `/usr/src/kernels/2.6.18-1.2798.fc6-i586'
make: *** [uvcvideo] Error 2

這是什麼玩意？

源碼包裡有文檔說明安裝方法否？依賴滿足否？
