+That's quite simple.
+On fedora :
+~ $ rpm --showrc | grep -i ' _libdir'
+-14: _libdir	%{_prefix}/lib
+
+On mandriva :
+$ rpm --showrc | grep -i ' _libdir'  
+-14: _libdir	/usr/lib
+
+Mandriva hardcode the use of /usr/ in the rpm macros file, while Fedora
+doesn't, letting people override %_prefix.
