Bugzilla Bug 155464

Several versions have been released including bugfixes for the dcfldd program.
Portage holds version 1.2.4-r1 which is still in testing?!.
Official upstream release has version 1.3.4 realeased stable since 12 feb 2006
cheers,

Renaming the 1.2.4 (not the 1.2.4-r1 !) ebuild works fine. NOTE: the fix for
wrong md5 generation on amd64 is in the official source, this is the reason
that 1.2.4-r0 and not 1.2.4-r1 should be used as a prototype.

Created an attachment (id=110049) [edit]
new version out: dcfldd/dcfldd-1.3.4.1.ebuild

Actually another version is out by now (released Dec 2006), by the versioning
looks like some "minor bugfox" which, according to the website, is:

Fixed an issue with error-producing blocks not being zero padding under BSD
systems.

The ebuild is attached. The only change (from 1.2.4-r0) is that ~amd64 is
readded to KEYWORDS and versionator is inherited and replace_version_separator
is used to mangle version string (since upstream decided on a fancy version
number of 1.3.4-1). 

Indeed a "diff -ru" between 1.3.4 and 1.3.4-1 sources shows only this:

So, I'd say it is safe to assume that 1.3.4-1 is the latest working version,
especially assuming that it is marked stable by upstream.

One last note. If forensics herd is Ok I can add this new version to the tree
myself (looking at how this was lagging for so long).

George

Thanks George. Please add.
