I added some debugging output to bzip2.jam at the end of the rule 
bzip2_config. Here is what I get with the following command line:

bjam -n -sTOOLS=tru64cxx65-042 "-sBZIP2_INCLUDE=/usr/local/include" 
"-sBZIP2_LIBPATH=/usr/local/lib" bzip2_test

NO_BZIP2=
BZIP2_SOURCE=
BZIP2_INCLUDE= /usr/local/include
BZIP2_BINARY= bz2
BZIP2_LIBPATH= /usr/local/lib

This looks good, AFAICT.

The generated compiler command line now is fine:

tru64cxx65-C++-action 
../../../bin/boost/libs/iostreams/test/bzip2_test.test/tru64cxx65-042/debug/bzip2.o

"../../../bin/boost/libs/iostreams/test/bzip2_test.test/tru64cxx65-042/debug/bzip2.o" 
  "../src/bzip2.cpp"

But the linker command line is still wrong, both the library search path 
and the library itself are missing.

tru64cxx65-Link-action 
../../../bin/boost/libs/iostreams/test/bzip2_test.test/tru64cxx65-042/debug/bzip2_test

    cxx -noimplicit_include -g -model ansi -version V6.5-042 -ieee

"../../../bin/boost/libs/test/build/libboost_unit_test_framework.a/tru64cxx65-042/debug/libboost_unit_test_framework.a" 
   -lrt -lm

Digging a little deeper, I was quite surprised when finding the reason for 
this: The support for <library-path>, <library-file>, and <find-library> 
has been missing from the tru64cxx65 toolset. :-( After adding this, the 
test passed ok.
