[Checkins] SVN: zc.buildout/trunk/src/zc/buildout/tests.py Now, when loading extensions, we search find links and the index.

[Jim Fulton]

Log message for revision 76778:
  Now, when loading extensions, we search find links and the index.
  
  Removed a test that was obsoleted by a setuptools improvement in
  handling failed downloads.
  
  Updated to reflect a change in bootstrapping. (I wonder why this
  wasn't needed sooner.)
  

Changed:
