temp_ptr is of type "boost::shared_ptr<CrystalInfo>", but the only
NamedProperty constructor that comes close is the one that accepts
"boost::shared_ptr<PersistentObject>". 

Since these are different types, the constructor can not be used. I can
only guess that at one point the boost::shared_ptr implementation
supported this kind of automatic casting of the contained class
pointers, otherwise the code could never have compiled.

To solve this: 

Since CrystalInfo is a derived from PersistentObject, you can replace
the line /PDBFileDetails.C:901 by 

   boost::shared_ptr<PersistentObject> temp_ptr(new CrystalInfo());


Hope that helps,
