I installed the client part of postgres on a Compaq Alpha running tru64
Unix 4 (or what they are calling it these days) using the openssl library.
This machine does not have random device and openssl's library insists
on some random data in order to start up. This prevented me from running
the software as downloaded. I made some changes to fe-connect.c to
read ~/.rnd for initial state so I could use the feature.

This isn't exactly a postgres problem, but it may be that you can check
for this case (no /dev/random and openssl) and call the ssl functions
to get random state from a file.

I am including the diff of changes I made to get this to work, though
it isn't a robust solution.
