I just backed out gspcav1 and compiled all the kernel drivers as modules and 
just plugged the webcam in; the kernel works out which ones to use. 

# lsmod | grep spca
gspca                 621584  0
gspca_zc3xx            48320  0
gspca_main             22656  1 gspca_zc3xx
compat_ioctl32          8256  2 gspca,gspca_main
videodev               34112  3 gspca,gspca_main,compat_ioctl32

However, you are not out of the woods yet! You will probably need the libv4l 
libraries installed to get spcaview to work. Skype and kopete still 
completely fail to find the camera. :( There is a long thread on the Gentoo 
fora about this.
