What directory is it being run from?  If it doesn't know where the Boost 
root directory is then the "intrusive_ptr" arg will be flagged as an error 
leading to the help screen.  So either... use the --boost=path option to set 
the location of the boost tree, or else cd into Boost's root directory and:

bcp boost/intrusive_ptr.hpp destination-path

to get just the header and it's dependencies, or else:

bcp intrusive destination-path

to get all of the "intrusive" library and it's dependencies - including 
those of the example and test programs - ie quite a lot of code.

Using "intrusive_ptr" as a name failed, because there is no such library 
name in boost... it's spelled "intrusive" instead.

It's not present in bcp - there was a modified version, but the 
changes/patches never got submitted :-(

You would need to contact the original author of those messages for more 
info.
