Even if he unindents the return, it will still return None if it doesn't 
find an i such that i["@name"] == p, as _pkgVersion only gets set if such 
a match is found.

Could this be cause by eg a string case match issue? Perhaps:

if i["@name"].lower() == p.lower():

would be a better comparison to use?
