 C<ExtUtils::Mksymlists> produces files used by the linker under some OSs
-during the creation of shared libraries for synamic extensions.  It is
+during the creation of shared libraries for dynamic extensions.  It is
 normally called from a MakeMaker-generated Makefile when the extension

 It takes one argument, a list of key-value pairs, in which the following
