[elephant-devel] 0.6.1 / OpenMCL / BDB

I finally figured out what was going on.  I hadn't realized that 1.1  
was only a x86_64 distribution (will only work on the new Core 2 Duo  
Intel chips or old PPC chips).

So there's a nice set of problems:

OpenMCL needs to link to 64-bit libraries, so we need to build 64-bit  
versions of libmemutil and libberkeley-db.

So in elephant.asd we need to add a line to the gcc compiler options:
    #-(or darwin macosx darwin-host) "-shared"
    #+(or darwin macosx darwin-host) "-bundle"
    #+(or x8664-target) "-arch x86_64"
    "-o" output-file

So that's great and I can load libmemutil without a problem.   
However, when it comes time to load ele-bdb, you also need a 64-bit  
version of berkeley db for the -ldb option, so you're going to need  
to build or download a 64-bit version of that.

I don't have time to do that just now, but if you want to give that a  
try and let me know how it works that would be helpful!
