But... the Portfile I attached said

patchfiles                  patch-configure

And I attached my revised patch-configure which said

-	LDFLAGS=`mysql_config --libs $LDFLAGS`
-	CPPFLAGS=`mysql_config --include $CPPFLAGS`
+	LDFLAGS="`mysql_config --libs` $LDFLAGS"
+	CPPFLAGS="`mysql_config --include` $CPPFLAGS"

to fix the problem with calling mysql_config. My Portfile also fixed  
the PATH in the configure phase with

configure.env-append        PATH=${prefix}/lib/mysql5/bin:$env(PATH)

so that mysql_config could be found. I tested this before attaching  
it to the email and it worked for me as sent.
