No problem, I'm still trying to decide if we should move ${DESTDIR} into the  
individual 'install' targets or not...

Hmm...I think it should be the other way around.  We've hacked up the         
install targets so that the default ${sbindir} and ${libdir} are /sbin and    
/lib respectively.  Therefore, we should define a variable called             
${staticlibdir} and have it equal to ${prefix}/lib by default perhaps?        
It makes sense to put liblvm.a into /usr/lib to me; it just the way we're     
doing it that I'm questioning.  I'd like to prevent installation problems     
because the user didn't type 'make -e sharedlibdir=/lib install', which is    
what would happen if we made the default libdir point to /usr/lib.   

Just FYI, the entire build system is going to get an overhaul after the 1.0   
release, so I will definitely be making sure these detail are kept in mind    
for that.
