 * The first-party stackwalker for BlueGene is structured as a seperate
 port from the third-party stackwalker (since one runs on an I/O node and
 the other runs on a compute node, which are different enough
 platforms).

 The first-party stackwalker is the 'ppc32_bgcompute' port, and the
 third-party stackwalker is the 'ppc32_bluegene' port.  Set the PLATFORM
 environment variable to which ever one you want to build and type 'make
 StackwalkerAPI' from the sw/core directory.  The resulting library will
 appear in sw/$(PLATFORM)/lib/.

 * You might need to modify the core/make.config file and set the CXX and
 CC variables to point to your appropriate BlueGene compiler.  They're set
 to use gcc right now.

 * The x86_64 port depends on libsymtabAPI, which requires libdwarf,
 libelf, and libxml2 to build.  If these aren't on your system, you can
 find download links on our web site at:

 http://www.paradyn.org/html/dyninst5.1-software.html

 If these are installed in a non-default place, you can modify
 sw/core/make.config.local to point to the correct location.

 * As mentioned, SymtabAPI won't work on the compute nodes right now, so
 the Frame::getName() function won't work in the ppc32_bgcompute port.
 Although you could still use SymtabAPI to look up symbol names off-line.
 Let us know if you think you'll really need this functionality, we can
 start investigating what it'll take to get it.
