I upgraded to chimaera from beowulf and rebooted.

Since, my stunnel4 services won't run. The port establishes from the
client, but then immediately closes.
stunnel4 log prints:
/usr/bin/stunnel: error while loading shared libraries:
libgssapi_krb5.so.2: failed to map segment from shared object

Google told me to reinstall stunnel4 and libkrb5-3. I did that-- no
difference.

I do see /usr/lib/x86_64-linux-gnu/libgssapi_krb5.so.2 which is a symlink
to /usr/lib/x86_64-linux-gnu/libgssapi_krb5.so.2.2

Nothing else has changed. Any hints?
