+The version of BerkeleyDB distributed by sleepycat.com installs in a
+version-specific directory by default, typically something like
+/usr/local/BerkeleyDB.4.7.  To have Configure find that, you need to add
+-I/usr/local/BerkeleyDB.4.7/include to cc flags, as in the previous example,
+and you will also have to take extra steps to help Configure find -ldb.
+Specifically, when Configure prompts you for library directories,
+add /usr/local/BerkeleyDB.4.7/lib to the list.  Also, you will need to
+add appropriate linker flags to tell the runtime linker where to find the
+BerkeleyDB shared libraries.

     sh Configure -de \

 locincpth is a space-separated list of include directories to search.
 Configure will automatically add the appropriate -I directives.
 
 loclibpth is a space-separated list of library directories to search.
-Configure will automatically add the appropriate -L directives.  If
-you have some libraries under /usr/local/ and others under
-/usr/you, then you have to include both, namely
+Configure will automatically add the appropriate -L directives.

+The addition to ldflags is so that the dynamic linker knows where to find
+the BerkeleyDB libraries.  For Linux and Solaris, the -R option does that.
+Other systems may use different flags.  Use the appropriate flag for your
