[sfepy] Problems with Linear Elasticity Example

Hi

I am trying to work out the example located on the following webpage

http://sfepy.org/doc-devel/primer.html#sec-primer

I am only trying to do the first piece of code, I am getting the following error and I am completely unsure what the problem is. I tried uninstalling and installing scikit-umfpack like bunch of times. Still do not know what the problem is. Any help would be appreciated on how to install umfpack. Other examples are running fine, except this one and elasticity is the only important problem for me.
