Summary: uses gem even when an install fails

Initial Comment:
Appears that in 1.9, at least

if you install a gem, and the installation fails

then you run 
require 'gemname'
it still loads it--in its very broken state.

At least that's about what I figure from scratching my head at this circumstance:

C:\dev\ruby\downloads\ruby-debug\pkg>gem search linecache -b

*** LOCAL GEMS ***

mark-moseley-linecache (0.5.2)
# note the lack of linecache -- removing mark-moseley-linecache seems to not affect the results, either

*** REMOTE GEMS ***

linecache (0.43)
mark-moseley-linecache (0.5.2)

C:\dev\ruby\downloads\ruby-debug\pkg>gem install linecache

Message:
I believe this was fixed prior to 1.3.5 as 1.8 and 1.9.2 trunk give me the same:

$ ruby19 -Ilib bin/gem install mysql -i ~/tmp/gems

mysql 2.8.1 is 100% verified 1.9
Update http://isitruby19.com/mysql with your experiences!

Building native extensions.  This could take a while...
