File loading problems using rdf-redland gem

[Rob .]

When I try to run a ruby script that uses rdf-redland I get the
following "No such file to load" error. Possibly it is not finding my
installation of redland?

ruby -rubygems parse.rb

/usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
`require__': No such file to load -- redland (LoadError)
from /usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
`require'
from /usr/local/lib/ruby/gems/1.8/gems/rdf-redland-0.5.1.3/lib/rdf/redland/store.rb:1
from /usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in

from /usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
`require'
from /usr/local/lib/ruby/gems/1.8/gems/rdf-redland-0.5.1.3/lib/rdf/redland/model.rb:2
from /usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
`require__'
from /usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
`require'

from /usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
`require__'
from /usr/local/lib/ruby/site_ruby/1.8/rubygems/loadpath_manager.rb:5:in
`require'
from parse.rb:1

Here's my script (parse.rb):

require 'rdf/redland'
include Redland
model = Model.new
parser = Parser.raptor
parser.parse_into_model(model,'allpolls.rdf')
p model.methods

I'm running on GNU/Linux (Fedora Core 1). I have rdf-redland0.5.1.3 installed:

gem list rdf

rdf-redland (0.5.1.3)

I have compiled and installed redland 0.9.18:

./configure --with-ruby
make
make install

Any ideas on how to prevent the "No such file to load -- redland" error?

Cheers,
Rob

Hi Rob,

Looks like you've found a RubyGems bug. I think we have seen
something similar since 0.8.1 was released, so we should be able to
figure it out pretty quickly.

Thanks for the report.

Chad, are there any work-arounds you can suggest in the meantime? I'd
like to give rdf-redland a whirl. ;-)

My first thought had been that I had missed a step when doing the
configure, make, install of the redland c library.

Thanks,
Rob
