You're not doing something like building the Tutorial1.hs from the top
of the build tree of your package? If so it'll be picking up the
local .hs files and ignoring the built and registered version of the
package.

You can check, use something like:

ghc --make Tutorial1.hs -i \
  -hide-all-packages -package base -package QuesoGLC

So that you know it must only be looking at the installed QuesoGLC
package.
