Getting Hugs to recognize new primitive functions

[Justin: Extraordinarily Lanky]

Hello all.  I've been attempting to find the answer to a question that 
I'm sure has been asked more times than any of us can count.  I'm 
attempting to use green card generated code for a project (why don't 
mutable arrays work?) and I can't get any information on where to put 
the generated .so file so that I can access the functions I have 
generated.  Am I going about this totally wrong or what?  I don't have 
it installed in any standard location (just an arbitrary directory off 
my home tree), so that might be a problem.  I'm running out of avenues 
and patience, so any help is greatly appreciated.  Thanks in advance.
