Well ... that is the default system (OS) library search path
(/lib:/usr/lib), but the clamav libraries get installed in
/usr/local/lib.

That's what I thought, but it does not appear to be looking there for
the unrar libraries.

I tried adding /usr/local/lib to LT_DLSEARCH_PATH, but that had no
(positive) effect.

So the test log file appears to be lying ... it sys it is checking
/usr/local/lib and can't find the unrar libraries, but they _are_
there.
Here is my configure line:
$ ./configure --disable-clamav --enable-check --disable-shared --enable-static
We are NOT running clamd (so we don't need the clamav user). the code
is just called as clamscan to scan individual files.

So it is finding it (/usr/local/lib/libclamunrar_iface.a), and opens
it, and then writes to standard error (fd 2) that is couldn't find it
and goes on.
The make tossed a couple warnings but no errors, could the unrar
libraries be broken ?
