I cannot really see that it is a Gentoo specific problem, but who knows.
I will try to get a CD of another distro somewhere, and get that on a
box to test - currently work/whatnot just keeps me pretty tied up :(
Another reason why I posted, is now that 2.6 is more widely used/tested,
its not only me that gets this, but other users as well - thus I hoped
that somebody with more time wanted to have a crack at it.

Back to the problem - on the same system, a 2.4 kernel works fine, but
a 2.5/6 kernel activates a race that creates an invalid entry.  I guess
the primary reason why not many people see this, is because most
non-Gentoo folk do not compile perl-5.8.0 from source.

Just grab the perl source, if you want, I can mail you the ebuild that
should give some direction in how to compile it, or grab your local
.spec, configure it (maybe with install location not in /), and then
just compile and finally install to a ext3 FS with HTREE enabled. 
Usually over here, it keeps on leaving an invalid entry to
..usr/share/man/man3/Hash::Util.tmp.

If it works fine (with a 2.6 kernel), I will go and bang my head against
a wall, and shutup until I can make time to try and track this - if not,
any ideas as to creating it outside the perl install (or rather the man
page part of the install process) would be great.
