libsbuild-perl 0.64.1-1ubuntu4 (amd64 binary) in ubuntu trusty

 The sbuild suite of programs (wanna-build, buildd and sbuild) are
 used to build binary packages from source packages. The wanna-build
 database tracks packages which require building; buildd schedules
 work from information it gets from the wanna-build database; sbuild
 does the actual package building.
 .
 This package contains the core library modules used by these
 programs.
