You can make a script to do this for you. There's multiple ways, but here's my way of doing it.
First move the real skype:
Next, create a launcher for your skype (this will open in gedit, you can alternatively use nano, or etc.)
sudo mv /usr/bin/skype /usr/bin/skype.real
And paste in the following: [32 bit users only]
gksudo gedit /usr/bin/skype
Save and you're all done. Launch skype, and you're good to go. You can try it from the terminal first, not that it matters...
Alternatively, for 64bit users, paste the following: [64 bit users only]
LD_PRELOAD=/usr/lib32/libv4l/v4l2convert.so /usr/bin/skype.real "$@"
