As an alternative, you can either:

1) Modify the opt program to statically link in the library implementing 
your pass.
2) Create a new program (based on opt) that runs your pass on a 
specified bitcode file.

SAFECode has done the latter; you can see what we did by checkout out 
the SAFECode source code 
(http://safecode.cs.illinois.edu/downloads.html) and looking at 
tools/Sc/sc.cpp.
