Bug#800628: pbuilder: pbuilder-satisfydepends-classic breaks on any versioned Build-Depends

[Daniel Schepler]

Package: pbuilder
Version: 0.218
Severity: important

(I also saw the same thing with pbuilder 0.217.)

When I try to build e.g. 0ad in my local setup, I get an error like:

W: no hooks of type D found -- ignoring
 -> Attempting to parse the build-deps
 -> Considering build-dep autoconf
   -> Trying autoconf
 -> Considering build-dep debhelper (>= 9)
dpkg: error: --compare-versions bad relation

Type dpkg --help for help about installing and deinstalling packages [*];
Use 'apt' or 'aptitude' for user-friendly package management;
Type dpkg -Dhelp for a list of dpkg debug flag values;
Type dpkg --force-help for a list of forcing options;
Type dpkg-deb --help for help about manipulating *.deb files;

Options marked [*] produce a lot of output - pipe it through 'less' or
'more' !
      Tried versions: 9.20150811+bpb2
   -> Does not satisfy version, not trying
E: Could not satisfy build-dependency.
E: pbuilder-satisfydepends failed.
I: unmounting /var/cache/pbuildd filesystem
I: unmounting /sys filesystem
I: unmounting /dev/shm filesystem
I: unmounting dev/pts filesystem
I: unmounting run/shm filesystem
I: unmounting proc filesystem
I: cleaning the build env
I: removing directory /build/chroot-amd64//24959 and its subdirectories

Putting debugging echo statements into
/usr/lib/pbuilder/pbuilder-satisfydepends-funcs, it appears it's trying to
execute "dpkg" "--compare-versions" "9.20150811+bpb2" ">= 9" "".

(Explanation of the "important" severity: I'm running a set of scripts here
to try to bootstrap the Debian archive from scratch using pbuilder - and
it's important for a series of trial runs that can't have Build-Depends
satisfied yet to complete as quickly as possible.  Therefore, I use
--preserve-buildplace - and that only really works with
pbuilder-satisfydepends-classic.)
