[Haskell-beginners] best way to proceed with package install

[Michael Litchard]

I am trying to install updated version of yesod-platform, and got this
output from "cabal install yesod-platform". Could someone please
advise on the most efficient way to proceed?

SHA-1.5.1 (new version)
asn1-data-0.7.1 (new version)
base-unicode-symbols-0.2.2.4 (new version)
base64-bytestring-1.0.0.0 (new version)
blaze-markup-0.5.1.1 (new version)
blaze-html-0.5.1.0 (new version)
cipher-aes-0.1.2 (new package)
data-default-0.5.0 (new version)
cookie-0.4.0.1 (new version)
date-cache-0.3.0 (new package)
file-embed-0.0.4.6 (new version)
hashable-1.1.2.5 (new version)
case-insensitive-0.4.0.3 (new version)
hspec-expectations-0.3.0.2 (new package)
hspec-1.3.0.1 (new version)

... many more, snipping ...
my concern was the next part of the message
