Here is an archive of my working version of PaStiX 
http://dl.dropbox.com/u/2234149/ricar.tar.gz
To build this you need to install Scotch
You also need to update the ricar/trunk/config.in file
Then you run make -j examples

After that you need this test case : 
http://dl.dropbox.com/u/2234149/shipsec5.rsa
And run 
STARPU_NCPUS=8 STARPU_NCUDA=0 STARPU_CALIBRATE=1 STARPU_GENERATE_TRACE=1 
STARPU_SCHED=heft ../example/bin/step-by-step -rsa path/to/shipsec5.rsa

I have made few modification on the source code since I noticed the bug but I 
hope it is still there.
