sorry should have explained better...

basically you link your library with the
-Wl,-soname=\${ORIGIN}/path/from/executable/to/framework
or your executable using an rpath containing
${ORIGIN}/path/from/executable/to/framework,

(some random amount of shell/makefile escaping will be required.)
see: http://ynform.org/w/Pub/TheTroubleWithOrigin
then link your library normally.

or the elf gabi.
