[Fieldtrip] Cabal install Errors Solution?

I managed to install FieldTrip by changing some of the source code. It seems that the vector-space package is too new, and it just needed to use some different functions, and add a little to the contexts of some functions. However, I'm not sure that the changes I made will preserve functionality because I'm not familiar with any of the code (neither the libraries nor FieldTrip). In any case, the reactive-fieldtrip example as described on the website worked fine. I made a tar.gz of my modified src directory if anyone whats to have a look.
