Well, some of you may have noticed this:

[greg@bulbasaur ruport]$ time ruby -Ilib -e 'require "ruport"'

real    0m0.573s
user    0m0.524s
sys     0m0.040s
[greg@bulbasaur ruport]$ time ruby -rubygems -e 'require "ruport"'

real    0m2.807s
user    0m2.320s
sys     0m0.248s

Gems was auto-requiring all the deps even though we said 'no thank you sir' in the gemspec.

Well to be fair, fastercsv would have been loaded anyway in Ruport 0.4.5, because it was required globally (with a rescue)

Still, that's not a big time hit. See on 0.4.5:

[greg@bulbasaur rel_0_4_5]$ time ruby -Ilib -e 'require "ruport"'

real    0m0.790s
user    0m0.696s
sys     0m0.084s

Luckily, RubyGems 0.9.0 will fix this.

If you want to see for yourself, go ahead and do:

gem update --system --source http://onestepback.org/betagems

[greg@bulbasaur ruport]$ time ruby -rubygems -e 'require "ruport"'

real    0m0.779s
user    0m0.696s
sys     0m0.068s

For the nerdy, I think this patch would solve the problem in 0.8.11, but definitely don't use it! ;)
