Various components of the piranha package have the path to the ipvsadm command *hardcoded* into the lvsconfig.c and nanny.c files as /usr/sbin/ipvadm. Hard coding paths in the source is a very poor coding practice, and results in broken configurations when the target is not located in the specified path. A better alternative would be to make this a configuration option at least in the the make file so the person installing the software from source can specify where things really exist on their systems. The ultimately and most desirable thing would be to use the GNU Autoconf/Automake tools so someone installing from source can easily specify on the command line where things exist. For example, one should be able to do something like: ./configure --prefix=/usr/local so they could install the pirahna package down the /usr/local hierarchy. Additionally, by using the Autoconf/Automake tools, you could simply specify a macro rule telling configure that you wanted to simply locate certain required software like ipvsadm within a configure.in file: AC_PATH_PROGS(IPVSADM, ipvsadm) Then, if ipvsadm were installed someplace else than where RH normally expects it, configure would find it, and if it didn't, building would fail. That way, you the software maintainer can dictate dependancies, while the installer can dictate preferences. At the very least though, this should be a Makefile option so the installer of the software can easily change the location of where to look for certain software.
