The is a Debian sid system on ppc64 so not exactly mainline. However the
IBM and Red Hat folks are going gangbuster on the IBM Power architecture
so I have to assume that ppc64 isn't too far out in left field.

Yep, seen that before too.  On a few things.  It is annoying because one
has no way to "look before you install" and one may end up with a
tainted install target.  However, yes, it does happen.

nix# env | sort |  grep "LD_"
LD_FLAGS=-L/usr/local/lib
LD_LIBRARY_PATH=/usr/local/lib
LD_OPTIONS=-R/usr/local/lib -L/usr/local/lib
LD_RUN_PATH=/usr/local/lib


Well heck .. that could be the issue.  Given that there was a previous 
version there :


nix# ls -lap /usr/local/lib/libunistring.so*
lrwxrwxrwx 1 root staff      21 Mar 27 21:45 
/usr/local/lib/libunistring.so -> libunistring.so.2.1.0
lrwxrwxrwx 1 root staff      21 Mar 27 21:45 
/usr/local/lib/libunistring.so.2 -> libunistring.so.2.1.0
-rwxr-xr-x 1 root staff 2552160 Oct  3 18:50 
/usr/local/lib/libunistring.so.2.0.0
-rwxr-xr-x 1 root staff 3056920 Mar 27 21:45 
/usr/local/lib/libunistring.so.2.1.0
nix#

So there it is ... well darn :

Thing of beauty :-)
