Hi,

i'm trying to compile the nmap 3.0 src rpm
now it fails on :

----
Compiling nmap
rm -f nmap
gcc -Llibpcap-possiblymodified  -L/usr/local/lib -Lnbase  -o nmap main.o
nmap.o targets.o tcpip.o nmap_error.o utils.o idle_scan.o osscan.o

/usr/bin/ld: skipping incompatible nbase/libnbase.a when searching for
-lnbase
/usr/bin/ld: cannot find -lnbase
collect2: ld returned 1 exit status
make: *** [nmap] Error 1
----

can someone give me a hint what this nbase is ? (which libary do i miss ?)
