+* Why does the OpenSSL compilation fail on MacOS X?
+
+If the failure happens when trying to build the "openssl" binary, with
+a large number of undefined symbols, it's very probable that you have
+OpenSSL 0.9.6b delivered with the operating system (you can find out by
+running '/usr/bin/openssl version') and that you were trying to build
+OpenSSL 0.9.7 or newer.  The problem is that the loader ('ld') in
+MacOS X has a misfeature that's quite difficult to go around.
+Look in the file PROBLEMS for a more detailed explanation and for possible
+solutions.

+* Why does the OpenSSL test suite fail on MacOS X?
+
+If the failure happens when running 'make test' and the RC4 test fails,
+it's very probable that you have OpenSSL 0.9.6b delivered with the
+operating system (you can find out by running '/usr/bin/openssl version')
+and that you were trying to build OpenSSL 0.9.6d.  The problem is that
+the loader ('ld') in MacOS X has a misfeature that's quite difficult to
+go around and has linked the programs "openssl" and the test programs
+with /usr/lib/libcrypto.dylib and /usr/lib/libssl.dylib instead of the
+libraries you just built.
+Look in the file PROBLEMS for a more detailed explanation and for possible
+solutions.
