debian etch upgrade, now 64bit machines cannot connect to backends (SSL)

[John Masterson]

For posterity and the list archives:

We believe we identified our problem. A previous administrator made 
source changes to our packages to remove the requirement of the 
frontends' SSL communication with the backends, since these machines are 
utterly private inside our network and he wanted to 1) make debugging 
easier, and 2) reduce performance and administration overhead.
