pkg thinks a package is installed, but its files aren't

[Pierre Abbat]

I tried to build one of my projects and it told me that cmake requires a 
version of libexpat that isn't installed.

[phma at zyxomma ~/crypt/build/bezitopo/dbg]$ make -j 3 && ./bezitest 
Shared object "libexpat.so.6" not found, required by "cmake"
