Hi,
I'm new user of Pysparse because i've heard about the excellent JD
eigenvalue solver in this package. I'm trying to install Pysparse on a
Ubuntu linux box. The compilation of Numpy 20.3 and Pysparse finished
with no error. I ran the Numpy test code in its demo directory, no
problem. But when I tried to run the Pysparse examples, I got the
following errors:
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=

I just couldn't figure out what went wrong with the programs. Would
you please give me some hint?
Thank you,
