[SciPy-user] umfpack installation (and dsolve error)

Hi, sorry for the newbie question.

I'd like to install umfpack, but am confused on what to do. I downloaded
easy_installer, but where do I get the full umfpack etc.

btw, the reason for this is that I'm having a problem with dsolve which I think
is a bug, but may just be my error.

for example:

a=matrix([[1,1],[1,1]])
b= matrix([.5,.5]).T
dsolve(a,b)
yields [.5,.5]
which is not a solution of ax=b  - I think...
(I also entered the matrix as sparse)

any ideas what's going on here?

thanks,
Eric
