[R-SIG-Mac]ggobi and Mac OS X

[Duncan Temple Lang]

I have been meaning to add this to the GGobi configuration, and will
get to it now that I know there is at least a small level of interest.
For the moment, you can run configure and then edit Makeconf and edit
the value of SHLIB_LDFLAGS. We parameterized it because we knew this
would arise, just never got to putting all the pieces together.

Also, just as a pointer for simplicity, if you untar the ggobi 
distribution and then from within the top-level directory
untar Rggobi, you could install both in one step as

  ./configure --with-R

Of course, we'll have to fix the configuration to get the -shared flag right.
