old libs removal

[Alexander Belikov <rbsda_(_dot_)_dis_(_at_)_gmail_(_dot_)_com>]

Hi all!

I'm folloving -current for a 6 month. As time goes by i've got a lot
of old\new libraries:

for ex. /usr/X11R6/lib
...
libXrender.so.3.1
libXrender.so.4.0
libXrender.so.4.1
...
libX11.so.8.1
libX11.so.9.0
...

...and so on.

Is there a way to remove all old binaries? It's not a problem for me
to write a short perl script to remove them. Is there any implemented
solution?
