[DRE-maint] Bug#696862: does not build on squeeze

[Marc Haber]

Source: ruby-ffi
Version: 1.0.11debian-5
Severity: minor

Hi

This is a backporting issue, and hence not important, hence severity
minor. I would appreciate help anyway.

I am trying to backport ruby-ffi to squeeze. However, this does not
work too well, as ruby packages are entangled to each other. I first
backported ruby 1.9.1 from sid to squeeze, and then proceeded to
install the following packages from sid on squeeze, which worked
without having to force dependencies:

gem2deb_0.3.0_all.deb
ruby-diff-lcs_1.1.3-1_all.deb
ruby-rspec-core_2.10.1-2_all.deb
ruby-rspec-expectations_2.10.0-2_all.deb
ruby-rspec-mocks_2.10.1-2_all.deb
ruby-rspec_2.10.0-2_all.deb
rubygems_1.8.24-1_all.deb

When trying to build ruby-ffi after this, build fails due to some
weird issue in ruby 1.8 (which is neither a backported nor a
distribution mismatched package, but the original from squeeze):

Can you give advice how I should continue here? If this is not
intended to work, please consider adding an appropriate build-conflicts
to the package.

Building ruby-ffi on sid works fine.

Thanks for helping.
