To head off future bug reports, how about including findssl.sh in contrib/
and having configure refer to it?

Like so:
checking whether OpenSSL's headers match the library... no
configure: error: Your OpenSSL headers do not match your library.
Check config.log for details.
Also see contrib/findssl.sh for help identifying header/library
mismatches.

    Good judgement comes with experience. Unfortunately, the experience
usually comes from bad judgement.

+#
+# "OpenSSL headers do not match your library" are usually caused by 
+# OpenSSH's configure picking up an older version of OpenSSL headers
+# or libraries.  You can use the following # procedure to help identify
+# the cause.
+# 
+# The  output  of  configure  will  tell you the versions of the OpenSSL
+# headers and libraries that were picked up, for example:
+# 
+# checking OpenSSL header version... 90604f (OpenSSL 0.9.6d 9 May 2002)
+# checking OpenSSL library version... 90602f (OpenSSL 0.9.6b [engine] 9 Jul 2001)
+# checking whether OpenSSL's headers match the library... no
+# configure: error: Your OpenSSL headers do not match your library
+# 
+# Now run findssl.sh. This should identify the headers and libraries
+# present  and  their  versions.  You  should  be  able  to identify the
+# libraries  and headers used and adjust your CFLAGS or remove incorrect
+# versions.  The  output will show OpenSSL's internal version identifier
+# and should look something like:
+
+# $ ./findssl.sh
+# Searching for OpenSSL header files.
