+I couldn't find a <flock.h> header defining a flock() prototype. That header
+comes with the flock server package (available on BeBits). You have to add
+the path to the directory containing the header via the environment variable
+CFLAGS (should contain -I</path/to/dir/of/flock/header>). Perl will be compiled
+without flock() support, if the flock server package is not installed or the
+header not found.
