[Bug-gnubg] Installing gnubg in my own directory

[Timothy Y. Chow]

I am trying to install gnubg on a university computer where I have an 
account but do not have admin privileges.  I believe the machine is 
running RedHat.  I downloaded

  gnubg-0.15-4.src.rpm

which I renamed "gnubg.rpm" for brevity, and tried to build it:

  % rpmbuild --rebuild gnubg.rpm
  Installing gnubg.rpm
  error: cannot write to %sourcedir /usr/src/redhat/SOURCES
  error: gnubg.rpm cannot be installed

I presume that the problem is that it is trying to write to directories 
that I don't have write access to.  How can I can force rpmbuild to write 
only to my own directory?
