Actually the idea is to nuke the srclib/apr directory completely and only 
rely on dynamic linking.  This would allow Ganglia to stay on top of any new 
releases of APR 1.2.x without having to merge or maintain source code.  I just 
didn't want to make the leap all at once in order to maybe smooth the 
transition.  However, if we think that the transition is no big deal, I'm ready 
to drop 0.9.7 now.  Dropping the static linking of 0.9.7 will eliminate the 
hacks I had to make in the configure.in and Makefile.am files.  Then when we 
move to use APR-Util expat, things will really get a lot cleaner.
