Hi,

that is cause by #2180. There is a patch for it, but the short
solution is to touch the pyrex file in question. Then everything is
back to normal.

Cheers,

Burcin did pop up in IRC a little while ago and reported the same
error. Neither touching the file, not a "sage -ba" nor applying the
patch from #2180 fixes the problem, so I am fresh out of ideas. It
only seems to happen on updates, i.e. in the other cases I saw the
issue a touching of a single file was sufficient. So there is maybe
more than one bug lurking in that code. Since I have been unable to
reproduce the harder problem yet any input (or even better solution)
is welcome :)

Cheers,

Michael

This is now #2295, there is also a patch attached to the ticket.

http://trac.sagemath.org/sage_trac/ticket/2295

The problem is caused by the symlink in one of the path components to
SAGE_ROOT. You can go to the "realpath" which doesn't contain the
symlink and build there to work around the problem.
