How do I solve the libXv.so.1 problem, so I may install SDL, smpeg, xine etc.?

[Miths/3K]

I've been trying to get a relatively decent videoplayer installed (besides the not so decent xmovie that ships with Mandrake 8).
I'm having serious problems though, because I don't have the libXv.so.1 library, but only libXv.a.

I have of course been around the Internet searching for information, and it seems that the problem is in XFree86 4.0.3, correct?

So far I have actually managed to create what seems to be the appropriate library (please bear over with me, my Linux knowledge doesn't really exceed the "edit-fstab-and-XF86Config-by-hand"-level yet).
I found the following line:

ld --whole-archive -shared -o /usr/X11R6/lib/libXv.so /usr/X11R6/lib/libXv.a

and thought, "hey, that looks usable" - and it did in fact create the libXv.so library/file.
I ran ldconfig (don't really know if that's neccesary), and made a symlink: libXv.so.1.
And guess what - it doesn't work!
SDL etc. can't find it.

What am I doing wrong and/or what can be done to solve the problem?

(There seems to be a similar problem with a library called libXxf86dga - is this solvable?)

I forgot to mention that the "ld..." line was found in one of the script files of OMS (Open Media System), which by the way seemed to install properly.

there is an rpm you can get from rpmfind.net for X libs
search for the file in name only install it, ignoring the warnings, and now i am able to use xine, albeit in a window, not full screen.
