calcru error on FBSD 5.0

[Murilo Woigt]

Hi, 
    I'm looking for an efective solution for the "calcru" error.
    I read many posts in many freebsd mail lists, but any solution solved the problem.
    I saw the problem listed on "fbsd known problems" ( http://www.freebsd.org/releases/5.0R/DP1/errata.html ) and it leaded me to this list.
    Does exist some kind of workaround, or corrective procedure for this problem?

Thanks in advance,
