unfortunately freeframe and freeframegl are not 64bit compliant yet. 
there's only one entry point of the plugins and every parameter is 
passed through there. hence the heavy use of casting is inevitable 
unfortunately.

check out the specs at freeframe.org if you take the time to port it to 
64bit. i can send you a simple example plugin that compiles in a 32bit 
linux.

best,
