VMware 6 doesn't fully intsall in Trusty

After doing a clean install of Trusty Tahr, I thought I installed VMWare Player 6, but when I start to run it I first get the error

Then it starts compiling four things:

-- Stopping VMware services OK

-- Virtual Network Device ... gets a red ! (CRASH)

-- Running Depmod OK

-- Starting VMware services ... gets a red ! (CRASH)

Then a new error pops up

This, of course, requires root and end up being a long file that is not very informative to a very pedestrian user.

Anyone have a clue about this? TIA
