fakeroot 1.5.6ubuntu1 (i386 binary) in ubuntu dapper

Gives a fake root environment
 This package is intended to enable something like:
   dpkg-buildpackage -rfakeroot
 i.e. to remove the need to become root for a package build.
 This is done by setting LD_PRELOAD to libfakeroot.so,
 which provides wrappers around getuid, chown, chmod, mknod,
 stat, and so on, thereby creating a fake root environment.
 .
 fakeroot requires SYSV IPC or TCP to operate.
