Subject: Help compiling Ruby Java Bridge on OS X?

Hi all,

I'm stuck so I thought'd I ping out to see if anyone else has done
this. Of course, asking for help is the best to be sure I find the
answer myself in 10 minutes. :)

I'm on the latest version of OS X w/an Intel chip. I'm running Ruby
1.8.4

I'm trying to install the Ruby Java Bridge and it needs to compile
native extensions. mkmf says it's failing because it can't find jni.h

Here's the trace:

jrr-mbp:~/Desktop/Ruby Java Bridge Projects/rjb-1.0.0 jared$ ruby

Could not create Makefile due to some reason, probably lack of
necessary libraries and/or headers.  Check the mkmf.log file for more
details.  You may need configuration options.

Here's the ext/mkmf.log file

jrr-mbp:~/Desktop/Ruby Java Bridge Projects/rjb-1.0.0 jared$ cat
ext/mkmf.log
have_header: checking for jni.h... -------------------- no

conftest.c:1:17: error: jni.h: No such file or directory

Any help would be appreciated!
