Is the build failing when building the DSA library (poolalloc/lib/DSA)?  
It looks like the poolalloc build system can't find the LLVM libraries 
that it needs to use for linking.

I have a couple of questions whose answers will help verify my theory:

1) What are the pathnames to your LLVM source tree (i.e., where you put 
the LLVM source code) and your LLVM object tree (i.e., the directory in 
which you the LLVM configure script)?

2) In Makefile.common in the poolalloc object tree (the place where 
you're compiling poolalloc), what are the LLVM_SRC_ROOT and 
LLVM_OBJ_ROOT variables set to?  They should match the pathnames given 
for the LLVM source tree and LLVM object tree above.

3) Did you compile LLVM first, and if so, did you do a Debug build or a 
Release build?  The poolalloc build system assumes that LLVM was built 
as the same type of build, so if you do a Debug build of LLVM, you need 
to do a Debug build of poolalloc, too.
