Solve the following python programming problem given the following code:
@ testhelp.context ('sysmodel') 
def testRedirect(self) : 
    self.addComponent ('bar:runtime=1.0', fileContents = ['/bar:runtime']) 
    self.addCollection ('bar=1.0', [':runtime']) 
    self.addComponent ('redirect:runtime=1.0') 
    self.addCollection ('redirect=1.0', [':runtime']) 
    self.addComponent ('foo:runtime=1.0', fileContents = ['/foo:runtime']) 
    self.addCollection ('foo=1.0', [':runtime']) 
    redirectRecipe = '
'.join (['class testRedirect(RedirectRecipe):', '    name = "redirect"', '    version = "2.0"', '    clearBuildReqs()', '', '    def setup(r):', '        r.addRedirect("foo", "localhost@rpl:linux")']) 
    (built, d) = self.buildRecipe (redirectRecipe, 'testRedirect') 
    self._applyModel (['install redirect=2.0']) 
    self.verifyFile ((self.rootDir + '/foo:runtime')) 
    redirectRecipe = '
'.join (['class testRedirect(RedirectRecipe):', '    name = "foo"', '    version = "2.0"', '    clearBuildReqs()', '', '    def setup(r):', '        r.addRedirect("bar", "localhost@rpl:linux")']) 
    (built, d) = self.buildRecipe (redirectRecipe, 'testRedirect') 
    self._applyModel (['install redirect=2.0']) 
    self.verifyFile ((self.rootDir + '/bar:runtime')) 
    redirectRecipe = '
'.join (['class testRedirect(RedirectRecipe):', '    name = "bar"', '    version = "2.0"', '    clearBuildReqs()', '', '    def setup(r):', '        r.addRedirect("redirect","localhost@rpl:linux")']) 
    (built, d) = self.buildRecipe (built, 'testRedirect') 
    self.assertRaisesRegexp (conaryclient.UpdateError, '^Redirect loop found which includes troves redirect, foo$', self._applyModel, ['install redirect=2.0']) 

    
    

    Fix the buggy line: (built, d) = self.buildRecipe (built, 'testRedirect')

#Here is Python code to fix the buggy line: (built, d) = self.

(built, d) = self.buildRecipe (redirectRecipe, 'testRedirect')
