Dsniff can't be installed !

[haneo]

I have downloaded dsniff and tried to install it i get this error:

[root@haneo dsniff]# rpm -ivh dsniff-2.3-5.i386.rpm
error: failed dependencies:
libcrypto.so.0.9.6.1 is needed by dsniff-2.3-5
libnids.so.1.0 is needed by dsniff-2.3-5
libpcap.so.0 is needed by dsniff-2.3-5
libssl.so.0.9.6.1 is needed by dsniff-2.3-5

so i downloaded and installed libpcap-0.6.2-9 like this:

[root@kerbachi dsniff]# rpm -ivh libpcap-0.6.2-9.i386.rpm
Preparing... ############################# [100%]
1:libpcap ############################# [100%]


OK now the libnids library

[root@kerbachi dsniff]# rpm -ivh libnids-1.16-2.i386.rpm
error: failed dependencies:
libpcap.so.0 is needed by libnids-1.16-2


!!!! I have just installed libpcap ???

I am lost:-( any help is welcome.
