+If the build of miniperl fails with a long list of missing functions or
+undefined symbols, check the libs variable in the config.sh file.  It
+should look something like
+
+       libs='-lsocket -lnsl -ldl -lm -lc'
+
+The exact libraries will vary from system to system, but you typically
+need to include at least the math library -lm.  Normally, Configure
+will suggest the correct defaults.  If the libs variable is empty, you
+need to start all over again.  Run
+
+       make distclean
+
+and start from the very beginning.  This time, unless you are sure of
+what you are doing, accept the default list of libraries suggested by
+Configure.
