Bugzilla Bug 29418

It seems that cdrtools and dvdrtools both install a bunch of binaries in the
same location, which can lead to package conflicts.  For instance, I've had
cdrtools installed for some time, but I recently bought a DVD burner, so I
emerged dvdrtools.  The dvdrtools version of "readcd" overwrote the one from
cdrtools, and now when I try to launch xcdroast, I get the following:

** WARNING **: Invalid readcd version 1.11a15 found.
        Expecting at least version 1.11a34
        Start xcdroast with the -n option to override (not recommended!)

Two packages really shouldn't install binaries to the same location; there
should probably be a block or something on the two packages.  The versions
installed on my system:

  app-cdr/cdrtools-2.01_alpha14
  app-cdr/dvdrtools-0.1.5
  app-cdr/xcdroast-0.98_alpha13

(some of those are a bit out-of-date now, but it looks like little has changed
in the ebuilds.)  Here are the binaries which seem to be in conflict:

/usr/bin/cdda2wav
/usr/bin/readcd
/usr/bin/devdump
/usr/bin/isodump
/usr/bin/isoinfo
/usr/bin/isovfy

Reproducible: Always
Steps to Reproduce:

You can try a newer version of the cdrtools with the dvdr-USE-flag set.

Furthermore I'll change the dvdrtools-package so that it provides virtual/cdrtools.
 Then xcdroast can use any of both tools.

Changes commitet.  May you test, if this is still an issue?

Closing, as the handling of cdrtools and dvdrtools has changed.  There is now a
cdrtools-virtual and one of the both apps will be declared as a blocker.
