....Really this belongs on the csound-dev list but as it started
here....

In remote.c the code reads
#ifdef LINUX
#include 
#include 
#endif
#include 

and this works on SuSE, Debian and Fedora (at least).  However on
gentoo the file  is frankly incomprensible

#ifndef _LINUX_IF_H
# include 
# define _LINUX_IF_H
#endif

#ifndef _LINUX_IF_H
#define _LINUX_IF_H
.....

So as _LINUX_IF_H is not set it reads , and then sets the
variable so it ignores the rest of the file.
I really suspect that the first #ifndef should use _NET_IF_H but it
does not.  I cannot see how one can use thee headers.
