That's normal.  AIX (up to but not including 5.2, I think) does not have a
/dev/random device.

That's actually caused by a problem in the AIX system headers that trips
up earlier gcc's, but openssh-3.7.1p2 will work around it on AIX 4.3.3.

Your options are: use openssh-3.7.1p2, upgrade your gcc or edit the system

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.
