At work we have a Makefile project that builds a dynamic library that

against a loadable bundle. When the bundle is built on a system running
Mac OS X 10.5, it builds successfully. However when the bundle is built
on a system running Mac OS X 10.4, warnings and errors like the
following ensue:
/usr/bin/ld: warning can't open dynamic library:
@executable_path/../Frameworks/<3rdPartyFramework>.framework/Versions/A/<3rdPartyFramework>
referenced
from: <path to dynamic library>.dylib
(checking for undefined symbols may be affected) (No such file or
directory, errno = 2)\
...
/usr/bin/ld: Undefined symbols:\
<Symbol in 3rd party framework> referenced from <dynamic library>
expected to be defined
in
@executable_path/../Frameworks/<3rdPartyFramework>.framework/Versions/A/<3rdPartyFramework\

What can be done to eliminate these errors and warnings so the build can
succeed on Mac OS X 10.4?
I will hazard a guess that you need to tell ld where to look for
dependent libraries that are referenced using @executable_path. You can
do this with the -executable_path "path_name" linker option to the 10.4
linker.
This option seems to have disappeared from the manpage on 10.5 :(

I configured the -executable_path option for the linker and that fixed
the problem. The code builds successfully on both Mac OS X 10.4 and 10.5.
