There is a change in Jpeg library between version 6 (6.2) and version 8.
As a dynamic library, the structure should be the same size for the
execution as for the compilation. The message you get is about such issue.

So either you can recompile povray with your current libraries (in dev
version) or you can install the shared libraries needed by your current
binary of povray. (but IIRC, Libjpeg6 & 8 are not compatible packages,
that might break something else)

Your main problem might be finding active repository with 10.4 (that's a
LTS that is 2 releases old: 12.04 and 14.04 are now out, so 10.4 might
soon become hard to get packages for: desktop is no more supported since
May 2013, and server is reaching that state in April 2015... two months
to go)
