Nobu:

Thanks for the response!  I applied the specified patch to util.c
however, it doesn't seem to have made a difference.  Dir.getwd works 
ok, I think the problem is in the ``.  I'll keep looking and if I find
something I will be sure to post the fix.

I will remain open to suggestions as I've hunted this problem off and on
for quite awhile.  Any suggestions are appreciated.

Regards,
Brad
