we are trying to install ffmpeg on our RH linux servers.
Trouble is that it works on one not on the other and we have no idea why. The working and the non working server have the same config information:

I wanted to ask whether this has something to do with the problem. before i try to figure out how come the libz.so appears i nthe one list and not the other.
btw the ld.so.conf files are identical.
It is a bit unusual that one version is not referencing zlib while the other is not. However, this should not cause a problem unless you are using a format that relies on zlib (several containers and codecs do). Not in this case.
The specific problem is spelled out in the error text:
FFmpeg and libvpx aren't getting along.
It looks like you compiled FFmpeg yourself from the latest source. Where did libvpx come from? Installed from a Red Hat RPM? Or compiled yourself? Did you compile on one of these RH boxes and then move the binary to the other one?
