IIRC one of the people having the issue with the 0.94x to 0.95 upgrade and
not having the link built correctly  by ldconfig eventually found they had
two copies of the lib one in /usr/lib and one in either /usr/local/lib or
/lib and ldconfig built the link in the wrong place. Any way you look at it
there is a problem as ldconfig should build the link against the most recent
lib version. And I think (99.9% sure) the default location for the lib is
/usr/local/lib. If you do an ls -lh /usr/local/lib/libclamunrar*
/usr/lib/libclamunrar do you find only one copy/version in one place?
