Overwriting library functions

Hi all,

I'm using a package that is still being updated to address unintuitive 
issues. (The package developer sent me a temporary function fix until
the next release.) Normally (when running on a single CPU), I call
reassignInPackage() to over-write the pre-set package function.

But it doesn't seem that the over-write is sent to the clusters (I 
usually use SNOW and snowfall) when I export the package. Can anyone 
recommend a method to reassign a function in a library so that it can be 
called properly on the workers?

Thanks,
Phil
