That's not really neccessary.  All "Permission Denied" errors usually
hint at a need for rootfulness.

MPlayer "make install" ignores the "--prefix=<prefix>" switch?  Why ?
When I say I want mplayer in some specific dir, I do so with good
reason.  Since when does a shell script know better than a human ?

I suppose you might argue that for someone new to Linux, it might be the
case that they are not aware of the LD_LIBRARY_PATH and/or ld.so.conf
issue.  But then, would they use --prefix ?

My policy is to always stick an app into it's own tree - that is, app
"xyzzy" goes into /usr/xyzzy.  This way, if the app is well - behaved,
there'll be

/usr/xyzzy/bin/*
/usr/xyzzy/lib/*
/usr/xyzzy/share/*

even

/usr/xyzzy/etc/*

Some smart apps will even take care of the library paths for me, not
necessarily by adding them to ld.so.conf.  I don't know how they do it,
and I don't care.  The point is, it's nice and clean.

Further, if I want to uninstall the app, all I have to do is rm -rf
/usr/xyzzy and I can rest assured that the app is gone, gone, gone,
without having left a single stray .so in my system-wide lib dirs.

Further still, if I want to test different versions of the app, I can
simply do:

mv /usr/xyzzy /usr/xyzzy-current
make install <- the new version I want to test
mv /usr/xyzzy /usr/xyzzy-new
ln -s /usr/xyzzy-new /usr/xyzzy
Test
rm /usr/xyzzy
ln -s /usr/xyzzy-current /usr/xyzzy
Compare results.

Generally, once I have the 2 or more xyzzy-<something> dirs I can flick
between them using a symlink like a dial.

I don't know ... my card doesn't have DRI either, so, maybe that's why
xvidix doesn't work with it. I know, DRI has nothing to do with xvidix,
but its lack points to a general lack of support for my card. BTW:

VGA compatible controller: ATI Technologies Inc Rage Mobility P/M AGP 2x
(rev 64)

I'm wondering:  Does anybody happen to know what chipset this card has
?  Is it mach64 ?  Rage128 ?  What is it ?
