A random shot in the dark is that you could try:
(1) installing the libssl-devel Ubuntu package with "sudo apt-get
install libssl-devel".
(2) rebuild the Python spkg in Sage:
cd SAGE_ROOT
./sage -f python
I have *not* tested this; it's just the first thing I would try, since
the error "no module named crypt" is a symptom of not having the crypt
module compiled into Python, which might happen if the libssl-devel
Ubuntu package isn't installed when you build Sage.

P.S. For a short while we used to include openssl with Sage, which
avoided such problems, but it turned out at the time that the openssl
license is GPL-incompatible, so it's somewhat unclear that we can
legally include it in Sage.
