Even if there were no incompatibilities, on OS X with Tcl and Tk (and 
other) frameworks, the version number is embedded in the path to the 
shared library and the linker normally creates an absolute path at that.

$ otool -L _tkagg.so
_tkagg.so:
   /usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current 
version 60.0.0)
   /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current 
version 1197.1.1)
   /Library/Frameworks/Tcl.framework/Versions/8.5/Tcl (compatibility 
version 8.5.0, current version 8.5.15)
   /Library/Frameworks/Tk.framework/Versions/8.5/Tk (compatibility 
version 8.5.0, current version 8.5.15)
