[boost] Can anyone please give me advice on regression test building?

This is my second attempt to get some help on regression test build. If I should post this to another list, please anyone give me advice to where I should post instead. Here is my question: I try to invoke bjam in subdirectory .....\boost\status (After having set TOOLS=vc-7_1 ) The last line I see is: Unknown suffix on <@boost!libs!spirit!test>./select_p_with_rule.cpp<template>normal - see UserObject rule in Jamfile(5). Obviously nothing has been built (no tests have been run?) Is this an error in the test Jamfile of spirit, or am I trying to do something stupid? Thank you for any help on this. Roland
