+Hi, Tomi.\r
+\r
+Those files are actually known to you because they are what "make\r
+install" installed.  The "./configure" script was invoked with the\r
+option "--prefix=/opt/notmuch-current".\r
+\r
+> and what does otool -L opt/notmuch-current/bin/notmuch output\r
+\r
+The otool program is kind of like the ldd program on Unix-like OSes.\r
+When invoked with the -L option, otool prints the shared libraries that\r
+the object file uses.  When invoked on a shared library, it also shows\r
+the install name of the shared library.  This is what I was trying to\r
+show was not an absolute path.\r
+\r
+In hindsight, maybe it would have been more clear if I had shown the\r
+output of "otool -L" on the notmuch binary itself.  It would have shown\r
+all the shared library dependencies with absolute paths except for\r
+libnotmuch.dylib which was just the file name which is why the dynamic\r
+linker couldn't find it when running the notmuch binary.  But I was\r
+showing the "otool -L" output on libnotmuch.dylib because that was the\r
+source of the problem (i.e. the install name was not set to an absolute\r
+path).\r
+\r
+I'm sorry for the confusing commit message.  As per David's subsequent\r
+email on this thread, I'll try submitting again with a better one.\r
+\r
+Regards,\r
