Re: problems with nmap and libpcap on gentoo

[sara fink <sara.fink () gmail com>]

here is the output of ldd -d nmap

linux-gate.so.1 =>  (0xb7fc5000)
        libpcre.so.0 => /lib/libpcre.so.0 (0xb7f73000)
        libpcap.so.0 => not found
        libssl.so.0.9.8 => /usr/lib/libssl.so.0.9.8 (0xb7f2b000)
        libcrypto.so.0.9.8 => /usr/lib/libcrypto.so.0.9.8 (0xb7dd4000)
        liblua.so.5 => /usr/lib/liblua.so.5 (0xb7dae000)
        libdl.so.2 => /lib/libdl.so.2 (0xb7da9000)
        libstdc++.so.6 =>
/usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libstdc++.so.6 (0xb7cc0000)
        libm.so.6 => /lib/libm.so.6 (0xb7c9a000)
        libgcc_s.so.1 => /usr/lib/gcc/i686-pc-linux-gnu/4.1.2/libgcc_s.so.1
(0xb7c8e000)
        libc.so.6 => /lib/libc.so.6 (0xb7b51000)
        /lib/ld-linux.so.2 (0xb7fc6000)

I re-emerge (recompile) nmap 5.00-r2.
