[DRE-maint] Bug#632553: gem2deb: dh_ruby ignores install directory

[Stig Sandbeck Mathisen]

Package: gem2deb
Version: 0.2.5
Severity: normal

*** Please type your report below this line ***

dh_ruby installs to a directory first binary package, and not to the
directory given as argument to --install

(on a multi package, this will be [...]/debian/tmp)

Example from build log, using the default debian/rules created by gem2deb:

#    dh_auto_install -O--buildsystem=ruby
# 	dh_ruby --install /home/ssm/Code/tmp/build-area/puppet-2.7.1/debian/tmp
#   Entering dh_ruby --install
# install -d /home/ssm/Code/tmp/build-area/puppet-2.7.1/debian/puppet-common/usr/bin
# install -D -m755 bin/puppetca /home/ssm/Code/tmp/build-area/puppet-2.7.1/debian/puppet-common/usr/bin/puppetca
# install -D -m755 bin/puppetdoc /home/ssm/Code/tmp/build-area/puppet-2.7.1/debian/puppet-common/usr/bin/puppetdoc
# install -D -m755 bin/filebucket /home/ssm/Code/tmp/build-area/puppet-2.7.1/debian/puppet-common/usr/bin/filebucket
# install -D -m755 bin/puppetd /home/ssm/Code/tmp/build-area/puppet-2.7.1/debian/puppet-common/usr/bin/puppetd

In the file /usr/lib/ruby/vendor_ruby/gem2deb/dh_ruby.rb, it gets argv
from the caller, but does not pull the installation directory from
there. Rather, it sets "package" to the result of "packages.first", and
installs to that instead.

debhelper's dh_auto_install will supply the install directory to dh_ruby
--install (se excerpt from build log). Please check if gem2deb can use
this to make source packages with multiple binary packages.
