>Description:
Libnet is a network library whose port is in /usr/ports/net/libnet
It comes with a utility called "libnet-config" which is meant
to simplify the life of the developer willing to use libnet, by
specifying the correct compiler flags for gcc.
For instance, 'libnet-config --cflags' should print
'-I/usr/local/include' and 'libnet-config --libs' should print
'-L/usr/local/lib -lnet'
This behavior is broken in the port, as 'libnet-config --cflags'
outputs nothing, and 'libnet-config --libs' only outputs '-lnet'.
As a result, the user has to manually add the relevant gcc flags
which defeats the purpose of having 'libnet-config' in the first
place.
>How-To-Repeat:
$ cd /usr/ports/net/libnet
$ make install
$ cd /tmp
$ cat << EOF > test.c
#include <libnet.h>
int main() { return 0; }
EOF
$ gcc `libnet-config --cflags` -c test.c
test.c:1: libnet.h: No such file or directory
>Fix:
Here is a patch for Libnet's configure.in script. Make sure to call
autoconf213 to rebuild the compiled configure script.
