I'm using latest fluxus Git with racket 5.1.1 (installed from sources
in /usr/lib) in Debian/Linux.
If I add -lffi at the end of the command, it manages to link but then
the error is repeated at the next scons invokation.

ffi looks a dependency of libracket, I wonder what's the assumed way
for getting the required LDFLAGS for it (I'm used to do pkg-config
--libs PKG, but can't even found a the .pc files in racket) and I'm
not a scons expert so I don't know how to immediately fix my build.

Help is appreciated.
