require issue

[Tobi]

Hi!

There seems to be an issue with the latest ruby1.9.1 causing a bunch auf
auto-bugs by Lucas' latest rebuild:

While this works:

$ touch /tmp/test.rb ; ruby1.9.1 -e require '/tmp/test'

This doesn't:

$ touch test.rb ; ruby1.9.1 -e require 'test'
internal:lib/rubygems/custom_require:29:in `require': no such file to
load -- rubygems (LoadError)
from internal:lib/rubygems/custom_require:29:in `require'
from internal:gem_prelude:167:in `load_full_rubygems_library'
from internal:gem_prelude:217:in `try_activate'
from internal:lib/rubygems/custom_require:32:in `rescue in require'
from internal:lib/rubygems/custom_require:29:in `require'
from -e:1:in `main'

It's seems ruby has an issue with requiring from a relative path and then
falling back to rubygems. And the cause of this seems to be, that '.' is
missing from the load path:

$ ruby1.8 -e p $:.include?('.')
true

$ ruby1.9.1 -e p $:.include?('.')
false

 That is caused by the magic in ruby 1.9.* which tries to fallback to
 using rubygems if a normal require fails. I'm not sure yet where we
 should go about that.

It might avoid trouble with unpackaged code, if this rubygems fallback is
kept. But there should at least be a useful error message. Currently it
just complains about the missing rubygems, not the library it tried to
load in the first place.

Attached is small patch that updates NEWS/README.Debian for the LOAD_PATH
changes.

... and another small patch, setting the html encoding to utf-8, because
the gem info might contain utf-8 characters. See e.g. nokogiri.

Thanks a lot!

I just noticed, that the timestamps of the files in the tarball are set to
 1970-01-01, which would cause lintian errors if such tarball is used as
upstream source.

Unfortunately it seems, gem's don't care about the timestamps. I took a
look at the rubygems source code and it probably might be easy to fix
this, but for now I think the best way would be to touch all files. See
the attached patch.
