Typically this error is a result of bjam running out of memory.  Allowing bjam to access a larger data section often corrects this problem. You can do this by issuing "export LDR_CNTRL=MAXDATA=0x80000000" in your shell prior to running "make install".

The best fix would be to add -bmaxdata:0x80000000 or the gcc equivalent as a link option when building bjam executable.

FWIW, I'm not sure how well VA5 will work with Boost 1.34.1
