Ok, I will try to make a collective response here to the issues 
that have been addressed in this thread.

* The *.so files have been installed with mode 644 since r3080 of 
  the toplevel Makefile (July 2001)... But I cannot see a reason
  as to why this was done, and I too think they should be installed 
  executable.
* We cannot use tar to install all libraries. This is due to the
  separation of the install_dev and the install_runtime targets.
  Neither can we use cp due to its incompatibility issues.
  Thus I still suggest using tar as per my previous suggestion,
  since it will mean the least changes to how the build system
  works.

Here is my suggested patch for these two issues:
