Caution: UHD in /usr/local/lib on Fedora X86_64

Previously, the package file for UHD placed the UHD shared libraries in
/usr/local/lib, even on x86_64
systems, where Fedora prefers libraries in /usr/local/lib64.

So, if you’d modified your /etc/ld.so.conf.d to have a configuration for
/usr/local/lib, then your
code would link with the instance of /usr/local/lib/uhd.so*.
Recently started UHD correctly
placing .so files in the preferred location on Fedora on x86_64
systems (/usr/local/lib64).

But because of search-order issues, the dynamic loader would find the
ones in /usr/local/lib first,
which become more and more obsolete. The “cure” is to remove the old
libuhd*.so* files from
/usr/local/lib on x86_64 systems, and re-run “ldconfig”, which will
cause it to find the newer ones
(now correctly placed) under /usr/local/lib64.

Just tripped over that one this morning, and thought I’d share my
experience.
