sockets availability during build

[Federico Beffa]

Hi,

I'm working on libupnp. The 'check phase gives the following error:

Initializing UPnP ...
** ERROR UpnpInit(): -208 UPNP_E_SOCKET_ERROR
FAIL: test_init

In spite of this, if I "guix environment" and run the test binary it succeeds:

Initializing UPnP ...
UPnP Initialized OK ip=192.168.0.5, port=49152

I suppose that sockets can't be accessed during the build phase. Is
that correct?

Thanks,
Fede
