[Cialug] [OT] Compilation problem

[Matthew Steven]

I think this is what I did last time I ran across this:

As long as you _remember_ to put them right back, you can briefly move 
the other .so files out of the linker path ( to /var/tmp for example ), 
run ldconfig or update-modules or whatever your distro prefers, do the 
configure, and move them right back.  Run ldconfig/whatever again once 
they are back to regenerate everything.

If you're going to disrupt symlinks, save a copy of the state of things 
before you start, just to be safe.
ls -l /usr/local/lib > /tmp/locallibs.txt

I'd also do a backup of the lib directory if you have the space in 
advance, it's easy to goof it all up.

tar cfv libs.tar /usr/local/lib
