I wonder if most people using notmuch on Mac OS X do so via +Homebrew or MacPorts. In this case, they would never encounter the +problem because notmuch has already been packaged for them. + +Both Homebrew and MacPorts address the problem but in different ways. +Homebrew uses install_name_tool to correct the install_name on the +shared library post install. Homebrew actually does this automatically +for all libraries (i.e. via fix_install_names) [1][2], so even the +package maintainer might never see the problem, and the formula has no +patch or indication of a needed install_name fix [3]. + +I don't think MacPorts automatically fixes install_name problems, hence +its notmuch port does apply a patch [4][5] that is exactly the same as +what I submitted. + +I checked Fink, but it does not appear to have a notmuch package. + +Personally, I use Pkgsrc, and it did not have this patch for its notmuch +package, but I submitted it, and it has recently been committed to the +-current tree [6]. + +Another possibility is that people running notmuch on Mac OS X may set +DYLD_LIBRARY_PATH [7] in their environment to point to where their +libraries are installed. If this contains the path where the notmuch +shared library is installed, then the notmuch binary would be able to +find the notmuch shared library even if its install_name is not a full +path. But this should definitely not be a requirement for running a +program; I think DYLD_LIBRARY_PATH should only be used in development. + +Thanks! + +Lewis + +[1] https://github.com/Homebrew/homebrew/blob/master/Library/Homebrew/formula_installer.rb +[2] https://github.com/Homebrew/homebrew/blob/master/Library/Homebrew/keg_fix_install_names.rb +[3] https://github.com/Homebrew/homebrew/blob/master/Library/Formula/notmuch.rb +[4] https://trac.macports.org/browser/trunk/dports/mail/notmuch/Portfile +[5] https://trac.macports.org/browser/trunk/dports/mail/notmuch/files/patch-lib-Makefile.local.diff +[6] http://cvsweb.netbsd.org/bsdweb.cgi/pkgsrc/mail/notmuch/patches/patch-lib_Makefile.local?rev=1.1&content-type=text/x-cvsweb-markup&only_with_tag=MAIN +[7] https://developer.apple.com/library/mac/documentation/Darwin/Reference/ManPages/man1/dyld.1.html
