Bug#694311: pbuilder: fails to --create with EXTRAPACKAGES=ccache

[Helmut Grohne]

Package: pbuilder
Version: 0.213
Severity: normal

I tried using the documented[1] approach to pbuilder. Unfortunately it
fails. Here is the tail of the create log:

| Package 'ccache' is not installed, so not removed
| build-essential is already the newest version.
| dpkg-dev is already the newest version.
| The following extra packages will be installed:
|   aptitude-common libboost-iostreams1.49.0 libcwidget3 libept1.4.12 libncursesw5 libsigc++-2.0-0c2a libsqlite3-0 libxapian22
| Suggested packages:
|   tasksel debtags distcc libcwidget-dev xapian-tools
| Recommended packages:
|   aptitude-doc-en aptitude-doc apt-xapian-index libparse-debianchangelog-perl libgpm2
| The following NEW packages will be installed:
|   aptitude aptitude-common ccache libboost-iostreams1.49.0 libcwidget3 libept1.4.12 libncursesw5 libsigc++-2.0-0c2a libsqlite3-0 libxapian22

| Need to get 0 B/6417 kB of archives.
| After this operation, 22.4 MB of additional disk space will be used.
| E: There are problems and -y was used without --force-yes
| I: unmounting /var/cache/pbuilder/ccache filesystem
| I: unmounting dev/pts filesystem
| I: unmounting proc filesystem
| I: cleaning the build env
| I: removing directory /var/cache/pbuilder/build//18320 and its subdirectories

After commenting out EXTRAPACKAGES=ccache, the --create works flawlessly.

Maybe you already have an idea what is going wrong here?
