[Boost-build] [boost-build] "Attempt to redeclare already existing project id"?

Hi all,

I recently started getting the above error from bjam when trying to build my
docs (note: the error is coming from tools/build/v2/build/project.jam#729).
I'm struggling to figure out what I changed to make it start doing this.

Can anyone tell me what the jam variable $(id) is supposed to represent
here? It is being returned as "boost/cgi" at the point of the error, but
none of my Jamfile.v2s are setting up any project name. I also noticed
$(location) is "libs/cgi/build" at the time of the error. I'm calling bjam
from "libs/cgi/doc".

Strangely, if the "build" directory has an empty Jamfile.v2, the error comes
up, but if I delete the directory, the error disappears. It's replaced by
other errors (including: "<tag>@rulename is present but is not the only
<tag> feature"), but I haven't investigated that yet.

What am I missing?

Regards,
Darren
