I had major issues with DSS.5.5.5 . After about a month fighting it, I downgraded to 5.5.0.
I am aware of the security issues in 5.5.4. My work was for development purposes only, if you are going though the same problems I feel your pain.
I used 5.5.5 with FreeBSD 6.2 and gave up. Once I downgraded to 5.5 the problems disappeared.
