I'm trying to build the 1.43.0 release from the tarball release.  After 
untaring I run bootstrap.sh with a user-specific install path.  It 
reports success with the bootstrap.  When I run bjam, however, I get the 
"error: Unknown target type EXE" error.  Searching the forums and lists, 
it looks like this occurred on Windows three years ago, due to paths not 
being handled correctly.  But I'm running on Ubuntu (9.10).
The exact error is:

~/boost_1_43_0/tools/build/v2/build/type.jam:146: in type.validate from 
module type
error: Unknown target type EXE

~/boost_1_43_0/tools/build/v2/kernel/bootstrap.jam:142: in boost-build 
from module
~/boost_1_43_0/boost-build.jam:17: in module scope from module

Am I misconfiguring something?  If I don't set a user-local path and 
just run

./bootstrap

Then I still get the same error.  I have two versions of bjam (3.1.18 in 
the distribution and 3.1.16 installed) which I've tried, and they both 
give me the same error.

System:
Ubuntu 9.10
Kernel 2.6.31-19-generic
gcc --version : 4.4.1 (Ubuntu 4.4.1-4ubuntu9)
bjam 03.1.18 (came with the boost distribution)
bjam 03.1.16 (installed on the system)

Thanks,
Alden
