Bug#573627: live-helper: LH_PACKAGES_LIST=rescue results in build failure for sid target

[Stanley Pinchak <Stanley.Pinchak@gmail.com>]

Package: live-helper
Version: 2.0~a8-1
Severity: normal

The file /usr/share/live-helper/lists/rescue AKA "rescue" fails as 
an LH_PACKAGES_LISTS entry for a sid target.  It requests a 
non-existent package, "msntp" be included in the chroot.  According to 
http://lists.debian.org/debian-legal/2010/03/msg00004.html 
this package has been removed for sid.  This bug requires manual 
intervention to bypass.  The package is available in lenny, but testing
and unstable do not have this package (for most arch in unstable).
I resolved this by surrounding the entry with  #if DISTRIBUTION lenny 
and #endif to restrict this package inclusion to lenny.
