Update Lenny prereqs for MARC::Record 2.0.1+

Update Lenny prereqs for MARC::Record 2.0.1+

2.0 requires MARC::Record 2.0.1+, and the packaged version of
MARC::Record is just 2.0.0. This causes mysterious failures of
various open-ils.search.biblio.* methods - so teach the prereq
installer to get a new enough version of MARC::Record on Lenny.

Aside: The juggling of prereqs in a single Makefile for multiple distros
is starting to get extremely complex, perhaps it's time to split them
out to a single Makefile per distro?
