[Build-common-hackers] Bug#534895: cdbs: perl MakeMaker 6.52 versus "make install PREFIX="

[Kevin Ryde]

Package: cdbs
Version: 0.4.56
Severity: normal
File: /usr/share/cdbs/1/class/perlmodule-vars.mk

The latest ExtUtils::MakeMaker 6.52 doesn't obey a PREFIX like

    make install PREFIX=/some/dir/usr

It seems to have locked down its paths at the ./Makefile.PL stage,
rather than expanding $(PREFIX) the way cdbs supplies from
DEB_MAKE_INSTALL_TARGET.

I'm not certain who's at fault.  MakeMaker is being unhelpful, but maybe
cdbs should use DESTDIR now.  I suppose PREFIX was from when MakeMaker
didn't support DESTDIR, but versions maybe since perl 5.8 have it.
Using

    DEB_MAKE_INSTALL_TARGET = install DESTDIR=$(if $(DEB_MAKEMAKER_PACKAGE),$(CURDIR)/debian/$(DEB_MAKEMAKER_PACKAGE),$(DEB_DESTDIR))

seems to help.
