gacutil exited with error 9009

Ok, this isn't one for me, right now, but I noticed this occuring in some code I'm working on. Now, I don't mess about with the gac (global assembly cache) in .NET - I'm a straight shooter - but I also like to note down issues with resolutions that might crop up later.

Henceforth, here is a blog post with a useful link:

And the article with the solution (original link):

Essentially, it's useful to be aware that VS does not take into account environment variables when compiling code unless executed with the right options, so best to use the full pathname of assemblies.
