+\r
+Sure, but you always set LD_LIBRARY_PATH instead of relying on RPATH.\r
+\r

+\r
+LD_LIBRARY_PATH is inconvenient as hell if you have multiple installs\r
+living in different places, i.e., you write /path/to/A/bin/notmuch and\r
+have it use /path/to/B/lib/libnotmuch.so.3 just because you placed\r
+/path/to/B/lib in your LD_LIBRARY_PATH at some point in the distant past\r
+when it was needed by /path/to/B/bin/other-thing that may not even be\r
+installed any more.\r
+\r
+This happens a lot more with languages other than C and when you have\r
+different compilers with mutually-incompatible ABIs or packages that\r
+didn't bother with soname versioning.\r
