require issue

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
