It is often useful on MacOS X to compile shared libraries with debug symbols in the so-called DWARF + dSYM format. The make gdb work better in many circumstances, e.g. when those shared libraries are Python modules written in C or C++ that one wishes to debug by running python through gdb. For each xxx.so library, there is a xxx.dSYM directory containing some extra information.
This is produced by first compiling the objects with -g and then by running the command-line tool dsymutil on the library:
dsymutil xxx.so
SCons does a great job at taking care of the first step with env.SharedLibrary(...) after setting CPPFLAGS or CFLAGS appropriately for that environment. On the contrary, it does not support the second step out of the box.
Hence this request.

Just for the record, here's my comment from the mailing list:
To do it robustly is a little bit more work than the [simple case], because (if I understand the man page correctly) it's actually producing a new .dSYM file as a side effect of the link now, and SCons should be taught about that side-effect file, similarly to Windows where it builds .dll and .lib files as a side effect of linking a .dll.

Bug party triage. Too complicated to settle on IRC; Gary to lead discussion in dev@scons and look at it again next time.
