Peter,

Very odd. You confirm that the file is present, but pkg does not seem to
know it. I can confirm seeing the same thing, but it is a bogus error as
rtld can successfully load and run cmake and ldd shows it as resolving
correctly.. Further, the pkg db does know about it as:
# pkg which /usr/local/lib/libjsoncpp.so
/usr/local/lib/libjsoncpp.so was installed by package jsoncpp-0.6.0.r2_1

It looks like a bug and it "affects some people", but it looks most likely
to be a pkg issue of some sort as the sharable is present and rtld seems
happy with it.
