compile on ubuntu - core/base fails

[nova]

Hi,

I hope this is the correct list for my problem.

I try to compile llvm/clang,gnustep,etoile like it is described in 

        http://etoileos.com/downloads/installtrunk/

But I am stucked at the part where it comes to gnustep/core/base. The
make command ends with:

 Compiling file GSHTTPURLHandle.m ...
GSHTTPURLHandle.m:1334:13: warning: implicit declaration of function
 'recv' is invalid in C99 [-Wimplicit-function-declaration] result =
 recv(fd, &c, 1, MSG_PEEK | MSG_DONTWAIT); ^
GSHTTPURLHandle.m:1334:29: error: use of undeclared identifier
 'MSG_PEEK' result = recv(fd, &c, 1, MSG_PEEK | MSG_DONTWAIT);
                                   ^
1 warning and 1 error generated.
make[4]: *** [obj/libgnustep-base.obj/GSHTTPURLHandle.m.o] Fehler 1
make[3]: *** [internal-library-all_] Fehler 2
make[2]: *** [libgnustep-base.all.library.variables] Fehler 2
make[1]: *** [internal-all] Fehler 2
make: *** [internal-all] Fehler 2

Is this a bug or did I missed something? How can this be solved? As
further informations I attached the entire output of configure
(temp-config) and make (temp-make). The machine os is an ubuntu 11.04
(32bit)

Thanks for your help up front.
