Hi, there seems to be a problem with notmuch on OS X when installed to a non-standard location: it's install name is "libnotmuch.*.dylib" rather than something like "$(LIBDIR)/libnotmuch.*.dylib", which prevents the binary from locating the library when things are installed in a nonstandard location. make works, but attempts to run it result in dyld: Library not loaded: libnotmuch.2.dylib Referenced from: /Users/mike/.homebrew/bin/notmuch Reason: image not found Trace/BPT trap I ran into this when installing it via the homebrew packaing system into somewhere other than /usr/local. I've fixed it for the time being by doing install_name_tool -change libnotmuch.2.dylib /Users/mike/.homebrew/lib/libnotmuch.2.dylib /Users/mike/.homebrew/bin/notmuch and in principle I could add a post-install hook to the homebrew formula to do this for other users of homebrew/OS X, but it seems like this is something that would be better fixed upstream. Any thoughts? A related issue has come up before: http://notmuchmail.org/pipermail/notmuch/2011/004094.html. Here's the discussion of this issue at homebrew: https://github.com/mxcl/homebrew/issues/8284. I am not on the mailing list so please CC me on replies. Mike
