WARNING: The netsnmp library is missing. This library is recommended.
Some programs (i.e. fsnmp, klpinfo and snmpyalc) can not be built without
this library.
Use your favorite package management method to install the library _and_ the
developer support. If there is no package available for your system you can
attempt to install from source. See http://sourceforge.net/projects/netsnmp/
for the sources.
