How about if you create an executable in the same Jamfile
as libkar.  I'd like to be sure that the problem is not caused
by some subtle difference between the targets.

I can't reproduce your problem.  Both of your attempts ought to work,
although listing boost_iostreams as a source is more correct.
What version of Boost.Build are you using?

Can you post the output of
  bjam -n
on a minimal project that demonstrates the problem?

For instance, in this project (with a dummy test.cpp)

# Project attributes
project
    : usage-requirements <include>.
    ;

# Project targets
lib libkar : archive.cpp archive_file.cpp boost_iostreams : <link>static ;

searched-lib boost_iostreams
    :
    : <name>boost_iostreams-gcc43-mt
    ;

exe test : test.cpp libkar ;

the link command looks like:

    "g++-4.3.0"    -o "bin\gcc-4.3.0\debug\test.exe" -Wl,--start-group 
"bin\gcc-
4.3.0\debug\test.o" "bin\gcc-4.3.0\debug\link-static\libkar.lib"  
-Wl,-Bstatic -
lboost_iostreams-gcc43-mt -Wl,-Bdynamic  -Wl,--end-group -g
