Hi

Does sage -ba stop at exactly the same file each space?
An input/output error often points at disk errors, though you seem
to have checked that already.

df -h can be used to check that there is enough space on the laptop
and dmesg | grep read can be used to check for disk level read errors.

Regards,
Jan

One of my students is having problems building Sage 5.3 on her laptop.

The install log is at http://sage.math.washington.edu/home/roed/mablang_install.log. The relevant bit is:

You might try typing 'sage -ba' or write to sage-support with as much information as possible.
Running sage -ba ran into the same error again. The md5sum of the tar ball is the same as that of sage-5.3.tar on sage.math. Any ideas?
