[boost] [jam] "don't know how to make trie.c"

I've just tried to run the Boost regressions tests for the first time in many months, and it failed when trying to build jam. ./bootstrap/jam0 -f build.jam --toolset=gcc --toolset-root= don't know how to make trie.c ...found 47 targets... ...can't find 1 target... ...can't make 1 target... ...skipped bjam for lack of trie.c... ...skipped 1 target... bjam build failed. Rene, did you forget to "cvs add trie.c" ? More generally, since I haven't done this in a while ... Can I still run tools/regression/run_tests.sh to run the tests for a number of toolsets? And should toolsets I've defined myself in $BOOST_BUILD_PATH still be found? Thanks, Jon
