Fix: append default GEM_PATH

[funal125]

I have tested it on jruby 1.7.6 and 1.6.8 also. they suffer the same issue.
Although jruby just has two default gems(jruby-launcher and rake).

I think the best way is add the default GEM_PATH back.
And I also try to remove the .gem in GEM_PATH

I think this would probably be the better fix. I dont even know why the default GEM_PATH was taken out. Probably in an attempt to let everything be defined in gemsets? and then I guess after that the "global" gemset request came in, to try to be that sort of "default fallback" (as far as I can tell, this is the order as things happened: #16, #18, #20). I personally would prefer to have the standard GEM_PATH added back in (see also #33).

Now having said all that.... I disagree with the implementation as done here. I dont want to call out to ruby just to get the standard GEM_PATH! (Hint: you should be using 'gem env gemdir' instead! as I alluded to in #33) You could then achieve this with a one-liner.

Ok, I got it.
Thanks a lot

[jf]

are you going to submit another pull request, Felix?

Now, we can use DEFAULT to include all default gems, this is especially useful for rubinius and jruby.
And I also remove .gem from GEM_PATH

[jf]

No.

[jf]

thanks, but I'm done with this pull request. a91d8af ... (leaving the version bump) is what I wanted.

[funal125]

I like your version.
Thanks a lot.

Now, i can go back to work with rubinius.

As mentioned in the commit, thanks for not letting go of this! you've convinced me to add the standard gem path back in; and I'm sure a lot of people will be happy with this...
