I see... looking at mainline, the toplevel Makefile.def has:

target_modules = { module= libffi; no_install=true; };

which would prevent libffi from being installed, I assume.

If the maintainers think installing libffi is the right thing to do, I can
propose a patch (assuming I can figure out how the autogen stuff works).

Sounds like a nifty project.  The boehm-gc in GCC is configured
specifically for gcj, though it should also be suitable for general C/C++
use.  Does Portable.NET have any special requirements, i.e. finalization
or type information?
