This might be true, but as far as I know, there's nobody who uses bjam 
on VMS, so we're in no beter position to fix things there than you.

bjam has a "-d+12" option which show the dependency graph. Maybe you can 
use it to see what's going on. Be warned that you've have to rename 
binary to "jam", if you want to use in in "compatibility mode".
