this sound to me that I made a mistake.
I typically when got a new pc, or a new installation of OS, just 
download setup.exe
and install "ALL" a/v package, in order to ease the future usage.
but now it typically takes 1 or 2 days to finish, considering also 
install cygwin port packages...
I'll install based on a "install-on-need" base...next time.

b.t.w., comparing with a "real" linux, like ubuntu, the current cygwin 
package maintenance tool
seems still in the raw stage , comparing with apt-get machanism ... not 
to complain..
