[racket-dev] Build failure on OS X

The recent change to `configure' makes it use `pkg-config' to add -L
and -I flags for libffi. But those should flags be added consistently;
that is, you should end up with a build that uses `libiconv' from
macports.

Did you run `configure' in a fresh build directory? If not, maybe you
have files leftover from a previous build that had different flags from
`configure'?

If not, can you show the compile line for "string.c"?
