boot.ci is in a contributed package (it's "Recommended", which means 
that a copy is distributed with R, but it is not part of R), so 
suggestions should go to the maintainer.  But you need to put together a 
simple example to illustrate the problem.  When I modify the first 
example in example(boot.ci) to specify type="normal", I get an error
