Is this also the case with the version provided by Kim-Ee Yeoh?

This is most unlikely a problem of ghc, i.e. I think there is some
problem in your programs logic. Can you provide further code possibly
restricting it to a minimal breaking example?
Also: have you tried running the function in question in ghci?

Thomas.

Just to clarify, because there seems to be some confusion in your comments
on Stackage. When someone sets up a project to use Stackage[1], you still
have full access to all packages on Hackage, there just isn't any way to be
certain the packages will compile reliably (which is the case with
installing from Hackage as well). And getting a package into Stackage is a
simple, open procedure[2] which anyone is allowed to participate in.
In other words: Stackage acknowledges the existence of every package on
Hackage, and can provide build guarantees for any package that is added to
its build-constraints file.
[1] Minimal procedure: run `wget http://www.stackage.org/lts/cabal.config`

Hi,
Sorry. I found my mistake. I figured my newness in the language was
showing, so I asked for help. But, to my surprise, I have been modifying
the function for the cache file and testing the data file. :Palm Plant:.
Sorry for wasting your time. It is working.
Richard

OK, having installed it, am I now at liberty to use the LTS instructions to
once again attempt to start an OpenGL project?
