Hi Gary, Bob, Thanks for your feedback!
In the end, I found Roumen Petrov replied to the list indicating that setting lt_cv_sys_lib_dlsearch_path_spec when calling configure might be able to solve this and indeed it did. http://lists.gnu.org/archive/html/libtool/2014-08/msg00004.html By passing lt_cv_sys_lib_dlsearch_path_spec="${stagedir}/usr/lib" (I'm not linking to anything under the system's /usr/lib so it's OK for me to omit it) I managed to get it not to add that directory to the rpath. I wish that this "sys_lib_dlsearch_path_spec" variable was better documented in libtool's documentation... I'd be happy to try to contribute but unfortunately I don't think I understand them well enough to give them a good description... Let me know if you think I could help with it anyhow.

This is on GNU/Linux and I'm using either the GNU ld and the gold linker (ideally I want both to work.) Both seem to support -rpath and -rpath-link but that doesn't seem to be part of the problem (as just adding the directory to lt_cv_sys_lib_dlsearch_path_spec was enough to solve it.) > GNU ld on GNU/Linux has these options: > > -rpath PATH Set runtime shared library search path > -rpath-link PATH Set link time shared library search path > > Notice that one is the path used for the installed library and the other is > for linking.

So in my actual case I'm installing libraries to a ${GNU_PLATFORM} subdirectory of /usr/lib where ${GNU_PLATFORM} is set to the GNU triplet. So, I'm actually passing ./configure both the lt_cv_sys_lib_dlsearch_path_spec="${stagedir}/usr/lib/${GNU_PLATFORM}" variable and also LDFLAGS="-Wl,-rpath,/usr/lib/${GNU_PLATFORM} -Wl,-rpath-link,${stagedir}/usr/lib/${GNU_PLATFORM}" which gets it to *add* the -rpath I want and to link to the libraries in the correct location. > I don't think that linking against libraries in DESTDIR is portable.

Well, in my use case I'm often/usually cross compiling so having the final libraries installed under /usr/lib is not really an option... It seems that lt_cv_sys_lib_dlsearch_path_spec solved the issue for me, but I'm not 100% positive how portable that is, if you can think of some reasons why this is not a good fix and if there's a cleaner way to accomplish this then please let me know.
