 That manual page references to "built-in standard directories", but
 does not define what they are.  Previously LD_PRELOAD set to not absolute
 path worked even for /usr/local/lib (as I understand because of ldconfig
 called for that directory).  I notice that net/proxychains that worked
 before on RELENG_9 did not work now (it calls any program with
 LD_PRELOAD=libproxychains.so, just install it and check shell script
 at bin/proxychains).
 
 > The attached patch addresses this problem as well.
 
 Yes, it works for /lib at least.
