Checking your choice of C compiler, libs, and flags for coherency...
I've tried to compile and run a simple program with:

        cc -O2 -Dbool=char -DHAS_BOOL -I/usr/local/include -L/usr/local/lib -o try try.c -ln
et -lnsl -lgdbm -ldb -ldl -lm -lc -lposix -lcrypt
        ./try

and I got the following output:
/usr/lib/libnet.so: undefined reference to `threadedAccept'
/usr/lib/libnet.so: undefined reference to `makeJavaString'
/usr/lib/libnet.so: undefined reference to `threadedWrite'
/usr/lib/libnet.so: undefined reference to `AllocArray'
/usr/lib/libnet.so: undefined reference to `threadedConnect'
/usr/lib/libnet.so: undefined reference to `threadedRecvfrom'
/usr/lib/libnet.so: undefined reference to `AllocObjectArray'
/usr/lib/libnet.so: undefined reference to `javaString2CString'
/usr/lib/libnet.so: undefined reference to `SignalError'
/usr/lib/libnet.so: undefined reference to `threadedSocket'
/usr/lib/libnet.so: undefined reference to `AllocObject'
/usr/lib/libnet.so: undefined reference to `threadedRead'
I can't compile the test program.
(The supplied flags might be incorrect with this C compiler.)      

You have a BIG problem.  Shall I abort Configure (and explain the problem)
[y]
Ok.  Stopping Configure.  

So what are the right flags?  (This was generated with Configure -d)  If I remove
-lnet will this solve my problem?  Will perl be adversly affected if I take out -lnet?
What's the best way to fix this?  Thanks in advance.
