Comment(by jhpalmieri):
With Sage 4.7.2.alpha2, I see problems with qepcad and sympow. I think
the qepcad problem should be easy to solve, basically as mhansen did
before:

Sympow will be harder to deal with, because of how the spkg is written: it
tries to write files to SAGE_LOCAL/lib/sympow. See
[http://trac.sagemath.org/sage_trac/ticket/9703#comment:9] for a possible
fix.
I'm attaching a patch to try to deal with the situation when you run Sage
for the very first time as a user without write permissions.
Finally, there may be other issues if you compile Sage but don't run it,
and then run doctests as a user without write permissions (the first time
doctests get run, they might write some files which don't need to be
written later). These issues should be fixed, too.
