+# (1) the socket interface is in libsocket.so -- this wouldn't be so hard
+#     for Configure to fathom...but it gets more tangled.
+# (2) if the system has been patched there can be libsocket.so.1.FOO.BAR,
+#     the FOO.BAR being the old version of the system before the patching.
+#     Configure picks up the old broken version.
