Sure, I do it all the time.

if you have the sources of FPC somewhere, in a terminal, change to directory
"packages"

Then do a

make clean 
make install PREFIX=/some/dir/on/your/system

That should do the trick. It will simply rebuild & install all packages.

You can do the same in the packages/fcl-json directory, but then some other
files that depend on fcl-json will also need rebuilding. So that's only when
you know what you're doing...
