[freeradius-server 3.0.8] errors while compiling

[ICHIBA Sara]

hey,

I'm trying to install freeradius-server 3.0.8. I installed successfully
talloc 2.1.0  but when I do ./configure in order to install freeradius I
have these errors and warnings

configure: WARNING: snmpget not found - Simultaneous-Use and checkrad may
not work
configure: WARNING: snmpwalk not found - Simultaneous-Use and checkrad may
not work
configure: WARNING: pcap library not found, silently disabling the RADIUS
sniffer, and ARP listener.  Use --with-pc   ap-lib-dir=<path>.
configure: WARNING: collectdclient library not found. Use
--with-collectdclient-lib-dir=<path>.
configure: WARNING: cap library not found, debugger checks will not be

--with-openssl-lib-dir=<path>, or --with-openssl=no (builds with   out
OpenSSL)
See `config.log' for more details

you can find the complete output of the compilation in the file attached.
I'm running on centOS 7.
