[gentoo-user] emerge --unmerge fails

[Hilco Wijbenga <hilco.wijbenga@gmail.com>]

Hi all,

I'm trying to unmerge some packages. They all fail like this:

centaur ~ # emerge --unmerge arora
 * This action can remove important packages! In order to be safer, use
 * `emerge -pv --depclean <atom>` to check for reverse dependencies before
 * removing packages.

 www-client/arora
    selected: 0.11.0
   protected: none
     omitted: none

>>> 'Selected' packages are slated for removal.
>>> 'Protected' and 'omitted' packages will not be removed.

>>> Waiting 5 seconds before starting...
>>> (Control-C to abort)...
>>> Unmerging in:  5 4 3 2 1
>>> Unmerging www-client/arora-0.11.0...
 * The 'prerm' phase of the 'www-client/arora-0.11.0' package has failed
 * with exit value -1.
 *
 * The problem occurred while executing the ebuild file named
 * 'arora-0.11.0.ebuild' located in the '/var/db/pkg/www-
 * client/arora-0.11.0' directory. If necessary, manually remove the
 * environment.bz2 file and/or the ebuild file located in that directory.
 *
 * Removal of the environment.bz2 file is preferred since it may allow the
 * removal phases to execute successfully. The ebuild will be sourced and
 * the eclasses from the current portage tree will be used when necessary.
 * Removal of the ebuild file will cause the pkg_prerm() and pkg_postrm()
 * removal phases to be skipped entirely.

 * Messages for package www-client/arora-0.11.0:

 * The 'prerm' phase of the 'www-client/arora-0.11.0' package has failed
