On RHEL6, this is how it looks right now:

kundratj at noe2 ~ $ locate /libQtCore.so

kundratj at noe2 ~ $ rpm -qf /usr/lib64/libQtCore.so.4

If I remember correctly, it's rather hard to persuade the linker to
ignore stuff below /usr/lib64 and use some other destination instead. I
tend to purge such unpleasant memories from my mind, though, so I cannot
provide much detail.

I suspect that RHEL6 would be on the top of the list of Linux
distributions to support.

I can imagine that updating a few lines in a project's build system to
make it link against a different library name would be the smallest
obstacle of any porting process, especially compared to other changes
required. Again, I might be wrong.
