FD_t is not something you can just cast to FILE, it's rpm's own io subsys 
type. Try something like this instead:

FD_t fdLogFile;
fdLogFile = Fopen("LogFile.txt", "w.fdio");
if (fdLogFile == NULL)
    ...
rpmtsSetScriptFd(ts, fdLogFile);

Fopen() and the related rpmio functions can be found in rpmio.h.
