I don't think you failed. I understood what you said, except it did not fully
work that way. I have to correct myself when I mention xine I actually meant
gxine which was installed by slackware. I never had xine in /usr/local. Xine
was actually automatically replaced by gxine if i remember right. I installed
slackware 3 times following your proposal mounting the old /usr/local later.
However each time I then installed another program, not a *.gz into
/usr/local but rpm2tgz, skype, gxine and totem failed to open until I
found my solution. And every time I move /usr/local/lib to the top in
/etc/ld.so.conf I get the same effect, programs won't open. Then disabling it
the programs open. So back down to the bottom of the list.

I have not tried un-installing skype and see if then gxine and totem will open
with /usr/local/lib on the top. Since all works fine now I will not try.
