This is getting closer. Please rebase your changes onto latest master and
force push the branch to refresh.
There are a number of places that still need to be updated to use
```TS_ADDTO_RPATH```:
$ grep LIBTOOL_LINK_FLAGS build./
common.m4: TS_ADDTO(LIBTOOL_LINK_FLAGS, [-Wl,-rpath -Wl,$1])
jemalloc.m4: TS_ADDTO(LIBTOOL_LINK_FLAGS, [-R${jemalloc_ldflags}])
lzma.m4: TS_ADDTO(LIBTOOL_LINK_FLAGS, [-R${lzma_ldflags}])
pcre.m4: TS_ADDTO(LIBTOOL_LINK_FLAGS, [-R${pcre_ldflags}])
xml.m4: TS_ADDTO(LIBTOOL_LINK_FLAGS, [-R${libxml2_ldflags}])
xml.m4: TS_ADDTO(LIBTOOL_LINK_FLAGS, [-R${expat_ldflags}])
Notice that these all use the ```-R/path``` syntax. This is because the
portable syntax for specifying the RPATH is ```-Wl,-rpath -Wl,/path```. The
```-Wl,-rpath=/path``` syntax appears to be specific to the GNU linker (at
least it is not supported by the OS X linker). When I tried the portable
syntax, ```TS_ADDTO``` doesn't do the right thing (it splits on whitespace).
You end up with something like this:
LIBTOOL_LINK_FLAGS: -Wl,-rpath -Wl,/usr/local/lib
-Wl,/opt/jpeach/lib
Finally, you need to append ```$RPATH``` in the main ```configure.ac```
since it is possible for ```TS_ADDTO_RPATH``` to never get called.
