+BUILDING PERL
+-------------
+Here's how to rebuild Perl to get the JNI extension to work properly:
+
+- Use all the defaults or whatever makes sense, but no threaded Perl 
+  and no interpreter threads, i.e.:
+
+  Build a threading Perl? [n] n 
+  Build Perl for multiplicity? [n] n 
+
+- When asked what libraries to use, type -lthread (Solaris) or -lpthread 
+  (Linux) and tack on whatever the default is at the end, i.e.:
+
+  What libraries to use? -> [-lnsl -lndbm -lgdbm -ldb -ldl -lm -lc -lcrypt 
+  -lutil] -lpthread -lnsl -lndbm -lgdbm -ldb -ldl -lm -lc -lcrypt -lutil 
+  (under Linux it's -lpthread, but for Solaris it's -lthread) 
+
+- Make sure that you do not use perl's own malloc, i.e.: 
+
+  Do you wish to attempt to use the malloc that comes with perl5? -> [n] n
