One way I can explain this is a broken system-wide install of libffi-dev
I don't know how this can be achieved, other than having multiple
system-wide copies of libffi,
or stuff manually removed.
The other possibility is that the linker is told not to look for
system-wide libffi - can this be achieved with -L and -Wl,-rpath ?
On the other hand, it's a bug in maxima, which does not try to check
for presense of libffi, just assumes it's there.
