Ok, I wasn't sure about what the tcpwrappers support exactly means. I 
thought it would be similar to compiling in an inetd compatibility mode, 
but thats obviously wrong.

Hmm ok, maybe I'll give this one a try.

Setting LDFLAGS="-lnsl" before configuring lsh with tcpwrappers support 
works. So thats a problem with the configure script? Shouldn't it work 
out all the libraries needed?

Thanks a lot for the help and suggestions, Pontus!
